This app is exactly what I was looking for. I wanted tool that would let me backup and/or sync directories on my phone to Google Drive, without also needing something installed on my desktop or a VPS. It performs that perfectly. I was initially concerned with how it would affect battery life, since I had instant sync turned on for all my profiles, but I’ve not noticed any significant battery drain. Overall, it does exactly what I needed to do. Definitely would recommend.
I love it. It does everything I needed to do syncing folders from my phone to my PC, individually, on a schedule, with options like verifying that I’m on Wi-Fi and charging. The only negative was that I spent quite a while trying to figure out how to make it work because it wouldn’t out of the box. I figured out that you have to enable SMB version 1 on the PC. Which Microsoft just disabled because it’s very very old and has some vulnerabilities. I hope they update it to handle SMB v3 soon.
TRULY POWERFUL APP. This app literally allows you to make regular backups of any folders you choose. It manages it in the background and doesn’t consume a great deal of the your devices computational power. It’s easy to use and setup. You can make backups of your settings. And it can backup folders on the external sdcard. It also supports two-way ftp transfers which allows you to create a sort of mirror between a local and remote directory. I HIGHLY recommend.
It is flexible but it is inconsistent. And the interface is a bit clunky. Sometimes it syncs things and sometimes not unless I open the app. I am thinking of switching apps. Also the sync log indicted certain pictures were copied when in fact they were not. I used this to sync files with my Synology NAS drive. The sad part is I actually spent money on this.
Works great! w/ one odd behavior Only complaint I have is the Sync seems to take a long time to actually start when my phone is in its dock using Ethernet. It acts like it’s not even trying to Sync then after 20-30 seconds it starts syncing. It also queues up every time I hit the Sync All button. So it starts syncing like two or three times in a row.
The best file and folder synchronization tool for one-to-one, one-to-many, many-to-one use cases available. It has been a reliable tool for keeping personal and business files synchronized & backed up across multiple phones, tablets, home NAS & SFTP, One Drive & Google drive since 2012. The only thing missing is a Windows 7/10, Linux and MacOS version to complete the ecosystem!
Some apps just do the job. No fuss, no muss, just do what they are supposed to do. FolderSync is one of those products with quiet excellence. If I couod improve one thing then I would make error/failure notices much more “in your face” (maybe send email or txt) However, this is really an excellent app and the Pro version is very much worgh the upgrade. If you need to competently back up yoir files, this is for you.
Incredible, painfully slow. Doesn’t run in background even with battery optimization disabled. Uploads everything wether it has to or not. 3 changed files? It’ll still upload all 10,000 files. No permutation of the settings helps. It is a hundred times faster to use a simple file manager to copy the whole directory. Support does not answer email.
Bought it for automated backups to my ftp server and that of course doesn’t seem to work. Neither instant nor scheduled syncs work. Not even an error about it in the history log. It just never initiates. I have to go into the app and manually press on sync all for it to work. And this only works while keeping the app open even while removing it from the background optimization stuff on the phone.
Works great. Highly configurable. Only complaint is that updates disable it, so if you’re not paying attention, you may not realize that your backups haven’t been running for weeks it more. Set notifications for success and failure so you’ll notice when it hasn’t run for a while.
The ability to sync with multiple cloud services and schedule when the syncing happens is great. Personally, I’m using it in two ways. 1. I have files on my phone scheduled to be backed up to a cloud service at night while I sleep. 2. I have a music folder on a cloud service that I sync to my phone when I choose. Using my computer, I’ll add new songs to my cloud storage. Then I sync the Music folder to my phone to get the updates. (Music streaming is great, but some stuff I prefer to have stored locally. I use less data that way.)
While it works great for automated syncing from android to cloud providers, I’m having a couple of problems and missing features: 1. It failed to connect to WebDAV, SMB, FTP devices in my home network, all other apps that provide this functionality work fine. 2. No versioning, if I modify/delete a folder locally, I’d like it to keep a copy of the old ones for x number of days on the remote. 3. No encryption.
I’d give it more stars if scheduled sync worked and if support was available. It did work fine a few updates ago. I sent a log as requested to see if they can tell what causes it not to sync anymore on a schedule, showing “error”, but never heard back. Otherwise, syncing manually (which is what I am doing now whenever I remember to do it), works okay.
Serious bugs I’ve come to observe over using Pro for several years. Time zone changes cause syncing of files that shouldn’t happen. A loss of signal caused the loss of tens of thousands of my files. Unreliable program when configured correctly, and I’ve lost faith in it to do what I paid for it to do.
10 years of great development made this an absolute life-saver. It’ll do whatever (transfer, mirror, sync), wherever (Local [Root/SD/USB|Hub], Network [DAV/FTP+/SMB+], Cloud [Drop/One/Google/Sugar/’too many’]), whenever (times/user-scheduled), however (file/folder/type/name), and whyever ([?…] settings/filters/options) you need to organize. Practically needs no intervention once set, and easy to update or expand after. Tons of files in many locations? – You’ll wonder how you lived without it.
Easiest method I’ve found to transfer files wirelessly on demand to always-on NAS. Configured cloud, SMB and SD card accounts fine although authentication was a bit tricky. Reasonable footprint. Nice interface and night theme. Custom scheduling functions flaky but eventually works although often later than at the scheduled time. Schedule execution requires background running, degreenification, and battery deoptimization. Filter setup is counter-intuitive. Developer has been helpful.
Latest version (a) broke all of my cloud syncs, and (b) shows nothing for the error so I have no idea what has changed or stopped working. After wasting my time trying to figure out what happened, I discovered that I needed to reconnect my Dropbox cloud storage account and that fixed the issue. It’d be swell if the error showed anything at all rather than no message. Adding back one star until the lack of error logging is addressed.
Great app – I can no longer use the MEGA sync feature however so this app is nearly useless to me as I schedule file backups between my phone and my mega account. If I log into my mega account via this app, it tells me i have successfully logged in followed by an immediate overlapping second error saying “cannot retrieve info from your provider, check internet connection or verify your account credentials”
I’ve been using this app to sync my photos and videos to my personal server for many years and for the most part I’ve been very, very happy with it. The only issue I’ve had is that it occasionally decides it’s not going to auto-sync when I connect to my home WiFi until I go back into the app and do a manual sync.
Exactly the kind of app I was looking for. Gives me granular control over which folders I want to sync from onedrive and when I want to sync it (schedule or manual). 5 stars all the way! Thank you very much
Great when it works. Folder pairs “break” regularly with app updates. Frustrating since they have to be reset or recreated. Conflicts and Error reporting are of little real use.
Very reliable. I don’t need to constantly check if it’s working, it always does its thing. Very reliable backup app for me.
Used to work well. Now no longer runs in the background, so pretty useless for my needs now. OnePlus 6T Android 11
Works perfectly. Ideal for automatically backing up your photos to a NAS instead of trusting them to a cloud service.
It works but when I set “to remote” and deleted 4 files from local and SyncAll, my remote files do not delete. Please correct the same
It would be great if we can have the option to toggle “withChuckedEncodingDisable” option for S3 compatible services.
This app is priceless. Backs up my all of my files from different machines to my phone and uploads them to the cloud. The deeplinks are a godsend for those who program small automation apps as well. It would be great if there’s an option for the app to remember devices by name and not by IP address.
I couldn’t use it to sync FTP, it has bugs. When a file is modified in the FTP folder, it is not updated in the destination folder. Also, there is no information to correct the “conflicts” and “file transfer failures”. Finally there are also bugs in the UI. It is simply not usable. I regret having paid for it.
I purchased the pro version to backup a couple of folders on my device. However the application does not run as a scheduled task in the background. I’m forced to open the application for the backup job to run. I contacted support and they said there was nothing they could do to resolve the issue.
Now you can only see sync progress when you sync all from the home page. You cannot go back to the home page to see progress when you sync individual folder pairs. Please fix !
Scheduled every specific hours to do automatic backup (upload), but notice the automatic does not work at all. Have to do manual backup only. This maybe a bug, hope that the support team to fix this problem asap.
Nice app n Good backup update, but missing sys all option , If I open app then manually I have click individual to sync.Pls add sync all option.Thanks
I found two bad things about this good app (I have the paid version of it): 1- An ugly icon. 2- The lack of a numerical indicator of the progress of the data transfer process (as is already found in competing applications).
Very good app to keep your files in sync across all digital platforms
Have used and recommended for years. Active and responsive dev, comprehensive and rich feature set, wide and seamless cloud service support, easy to use, and just works. One feature I’d like to see is the option to automatically connect a VPN if not connected to a whitelisted access point at sync time. Otherwise, this is the sync app that ticks all my boxes, and there’s no close second.
I purchased this to backup my photos from several devices. Then I came with the great idea of using it to sync folders between devices (images, ringtones, music, etc) But it failed miserably, I deleted a file from the device using the phone’s file manager, and it never synced to the cloud; I moved files in the device and expected them to be moved in the same way and I had a folder with the files I moved and the files in the original place. (all by using instant sync) What a mess. I’ll stick to backup all my files manually now that I’ve seen it doesn’t work.
I use the app to backup my pictures, (titanium backup) apps, and even my entire phone to my PC. Mostly it works fine but sadly doesn’t seem to work with smb2. As smb1 is insecure I have disabled it on all my systems and most file explorer apps work fine. This has meant I have to run an sftp server on any PC I wish to sync to which is a bit annoying.
This app is still one those ‘old reliable’. Been using this ever since I used a Galaxy Note 2. Combined with a file manager that can also act as a file server (WebDAV), it’s a really reliable way to sync things across devices. Also been using it to sync with my One Drive and Google Drive accounts with no problems. User interface takes a bit getting used to, though. First timers should set up Accounts first before getting to Folderpairs.
Uploading to Amazon Cloud Drive stopped working around 2 weeks ago. I don’t want to run the risk of losing my files if I lose my phone, and I don’t want to change my cloud storage provider. So, my only option is to ditch FolderSync for something else. A shame, because I liked the product. Contacted support and submitted logs, without any reply from the team. This seems to be ran by a single person, bear that in mind if you decide to buy it and rely on it.
Amazing and very versatile data syncer. Can’t even find anything as versatile as this on Windows. However, please could you implement the following: – An option to terminate a sync that’s currently in progress and never run it again until reconfigured? After restoring my sync pairs from an earlier configuration, it appears to now be in an infinite loop, constantly crashing the Media Scanner service on Android and reattempting to sync over and over until I force end the entire app, shouldn’t have to clear the entire app data just to fix that 1 sync pair. – Give us a means of setting a specific local directory as an “account”. I just upgraded my Note 8’s 200GB MicroSD card to a 512GB MicroSD card, and due to the way Android handles external storages with unique IDs, I have to now change each and every directory that was syncing with my old MicroSD to the new one. It would be a great time save to have %EnvironmentalVariable% like shortcuts.
I would love to have a desktop version of this app, I have used an old phone as an in between just to have it sync several sources. this app is great if you have many cloud services you need to sync. edit:prev error where I lowered stars. my fault. my next cloud server may be misconfigured with bad web redirection. back to 5 stars with you after trying another ddns port to my home.
Want to love it but it has weird problems. I have a sync setup for every 15 minutes but every time I leave my home wifi network it doesn’t run again when I return until I open the app. Also for some reason it decides there are “conflicts” but the log is just a list of files with no explanation of what the conflict is. The FAQ is not helpful and there’s no other documentation or help that I can find.
The idea is quite strong but the implements falls short of the features offered. While creating folderpairs, it does not let you move around the folder structure in any of the online storage services like Google Drive, Dropbox etc. This was the crux of the app and it fails to deliver. Will consider change in ratings when things improve.
The most powerful sync tool on Android. Love the new material you. It solves the sync issue for apps that don’t support sync feature. It also can auto manage local folders to keep your storage clean.
Downgrading my assessment as the auto sync using Google Drive fails daily now saying it can’t resolve DNS. If I manually run, it’s fine which doesn’t seem very “Pro” to me. I have the auto routines configured to run over any connection (2g, 3g, 4g, 5g, WiFi, etc.), but I still get this error with a 400Mbps WAP a mere 6′ away from my Pixel 7 Pro. Please resolve.
The recent app updates and UI changes are remarkable. This is truly a game changer for my needs. This app is excellent at what it does. I wish I could get it to work with my local Minio server though.
Configured: with Wifi. State: in Wifi. Forcibly pressing “sync now” result: “Should any connection be used?!” And sync never starts. Any cloud.
I use this to sync emulator saves, it’s well worth the money. Edit: currently non-functional on my phone (stock ROM) as I can’t link any accounts. This has been broken for almost a year now. It still works fine on the $30 tablet I threw LineageOS on, though… Maybe I could import the app backup from that device or something.
Works great for my cases (Yandex.Disk, simple filters, one way, two way, instant). Works even on Meta Quest 2 after some hacking around Yandex.Disk OAuth. To developer: one key improvement to make it even easier to set up filters is to simply list the directory tree with checkboxes next to each directory. That is exactly how partial sync is configured in the major cloud storage apps.
Can’t access root on a rooted phone using Android 11 (other apps working fine). Would be glad if you could solve the issue. Thanks!
08/11/2022 And again to day ,and again I can investigate to solve . I SWITCH TO SYNCTHING I think. Again : failed after upgrade exhausted available authentication methode You pay for something and then developper change behaviour But you can investigate to solve it
One of the best app to sync your files across your shares, cloud accounts and storages. Works perfectly and provides a load of options to tweak the sync as per your needs. Go for it.
Newest version fails to allow rooted phone to access /data/ folder from root directory of phone. Just sits and spins animation and does not complete task. All other folders including /system are accessible.
Was great once, lately comes with random bugs every update. Current version crashes when clicking “files” or “about” tabs, support page asks to enable debug logs on “about” tab… Yeah, I’d love to, but *crash*.
An all around client for cloud/FTP/SMB servers. It does what I need. Transfers speed on android are a little bit on slow side (Around 2MBs).
Need to have And + OR operations for filters in order to compine multiple conditions together, now it only checks if any (not all) filter is true
Overall a decent app. It does what it says, and it does it well. What knocks down a star for me is that there is no app action for forcing a sync. There is a widget to do that, but that does not integrate with voice assistants like google voice or bixby, so I can’t e.g. automatically sync my notes folder after closing my notes app. Otherwise it’s as I said. It works well, and it mostly stays out of my way. Boring in the best sense of the word, and definitely worth the small sum
Fantastic sync app, easy to use, sports many destinations, I didn’t notice any excessive battery drain, interface looks good. It really improved my productivity with sending scans and notes to my own Cloud automatically. I’m sure I could find many more creative ways to use it The only improvement I wish for is a way to keep 2 copies of a file if it’s been modified at both ends (one marked as sync conflict). It would be even better if it handled merging of changes like git
High quality, professional, file synchronization tool. Used for a few days & so far, *FolderSync Pro* kept my working files synchronized between our private ftp server, and my mobile. No version control errors. Instant, intuitive setup. No bloat or gimmicks. Love the two way – including deletions – functionality, and directory cloning. Scheduling and connection type for sync keeps the app data-inexpensive and unobtrusive. Clearly, tons of thought and testing went into it, which I appreciate.
EDIT: Latest update fixed all the below issues 🙂 I’ve only used it to sync over LAN/SMB (not over the internet), but it does that very well. — Needs to be updated (to a newer SDK?) – it can’t read what WiFi network I’m currently connected to, which is critical as I’m syncing to a local server. I think it might be because WiFi needs the location permission, and I could only grant it access “while the app is in use” on Android 10 (OnePlus 7 Pro). Also: notifications don’t work at all.
Fantastic app till Android 12. On Android 13, the app needs proper optimization. The app fails to sync reliably in the background on Android 13, and keeps giving sync errors multiple times every day. As the app isn’t able to sync properly, it keeps running in the background retrying to sync, and ends up draining a lot of battery without actually syncing files. Developer should look into this and fix the problem on Android 13.
Changing accounts for a folderpair (as in SFTP -> SMB transfer protocols, not password) reset the remote path to the root folder of the share silently as well. This in turn wiped out a whole volume with collected backups, 4 Tb of files, on the next scheduled photo sync. That shouldn’t ever happen without a warning. Period.
I use this app to backup all my photos and videos, and not just the phone’s gallery, but also files from WhatsApp, Instagram, and the phone’s screenshots and screen recordings. I also sync a notes archive locally, to view and edit with Markor (another app). Worked fine for me with both Dropbox and OneDrive. This app alone justifies my use of Android ❤️
The best back up and sync app on android. Bought the life time license, and using it until now without any problem. Hoping the developer will keep the app alive for future android version.
This app has been serving me reliably for years. I used it to backup my data to the Cloud and locally to a NAS.
The new UI so good. Loving it. The quality of this app has dramatically stepped up. Pls develope more productivity apps. 👍
Surprised, impressed and pleased. This work simply and reliably.
Statefarm pro. Great app. Don’t get the icon choice. 😁
