FreeFileSync Forum

I also would like that feature, comparison using only filenames, be added. That could help circumvent some bugs such as modification time being altered to current time when transferring from Android to PC. That would allow the use case of transferring pics from a phone where each pic has a distinct ...

You're not alone. It's a problem that has occurred again and again, including in my device. I have done some research about this issue before, and what I found matched with what you have observed: it is a software issue, not a hardware one, specifically on the MTP implementation. Here are some solut...

I think two-way already covers your goals. On default, it propagates the latest changes which is what you want. Sync conflict only occurs if you edited the exact same file on both sides (e.g., editing File1.txt on the left folder and editing File1.txt on the right folder will confuse the program, on...

I haven't tried Cryptomator yet, only read discussions about its latest file extension, .c9r, being considered as ransomware by OneDrive. Though thanks for letting me know your experience, I may try it in the future. Btw I currently settled on using password-protected 7z archives instead, using 7-Zi...

Maybe you have more than 1 instance of the app opened? Bizarrely, FreeFileSync default on allowing multiple instances. The time listed will be the one on the last instance you closed. If for example, you have 2 windows open: A - the 1st window you opened but never did any syncing B - the 2nd window ...

It doesn't work with Cryptomator? There goes my plan to try that app...

Thanks for replying, though I have checked both but none satisfies my needs. For VeraCrypt, the problem is it's a single file. Syncing a 10GB file is quite fast on a local drive, but may take hours to a cloud storage. I can break it down over several containers, but that would be tedious to update. ...

Is there a way to create encrypted online backups with FreeFileSync, whether alone or in combination with another program? I know that this isn't the main goal of the app, that there are apps designed for that purpose. However, I noticed that such apps are often not user-friendly, having CLI instead...

Copying multiple small files are always much slower than copying 1 large file, even if they have the same total, due to various reasons: https://superuser.com/questions/808279/why-does-copying-individual-files-take-so-much-longer-than-one-large-file That's why they are not comparable, especially sin...

Did a bit of research and found that this has occurred again and again before: 1. https://www.techsupportforum.com/threads/solved-free-file-sync-windows-error-code-5-access-denied.679585/ 2. https://freefilesync.org/forum/viewtopic.php?t=7008 3. https://freefilesync.org/forum/viewtopic.php?t=6147 4....

I think it would be better to treat the freemium model as a spectrum, where on one side lies totally free, while on the other totally paid. With that, I would agree that FFS is freemium, but at the same time, it lies very near to the totally free side. Aside from being feature-packed and having supe...

Fixed! Turns out the MTP device proposes a buffer size of only 1 byte, which is unexpected for FFS and it deliberately crashes. The reason for this size is that the file in question also has only 1 byte as content, and the "optimal buffer size" is trimmed to the file size for whatever rea...
