FreeFileSync Forum

Yes, this helps.

I saw these hangs when trying to rename a file on some MTP devices. For whatever reason the smartphone gets freaked out and blocks for 30 seconds, apparently doing nothing.

To verify you could test disabling the DB file (which renames the file sync.ffs_tmp to sync.ffs_db).

when synchronizing from mtp (cell phone) to pc over usb cable, it takes a few seconds until I see 100% done,. Then there is the dialog for 45s until message that all is done. My idea is that its about creating app-file sync on mtp storgage. Consistent with this, when I sync from pc to mobile, it takes ...

That's just normal behavior. You can select any folder for versioning, doesn't matter if local, (S)FTP, MTP, or Google Drive: https://freefilesync.org/manual.php?topic=versioning

@dave_m

You are welcome.

One of the things that's nice about foldersync is that it supports about a dozen Cloud providers including Google and Microsoft and many others so I'm a Microsoft user and have storage on one drive and I can use that program to back up files to OneDrive. It does my text ...

Hi, thank you for your responses. It's been a busy week, so I haven't had time to look into this topic. In the meantime, I have found another open source application that also works correctly.

@dave_m,

Hi,

I installed the f-droid primitive sftp server and it set the date of each file to today's date, just like it did for you. It's the apps fault.

Try the one I recommended, it works correctly!!

Hi,

The free SFTP server that I recommended allows FFS to preserve all of the original date and time stamps.
I don't have all files with the same date or the date I run the sync.

You can also approach the problem from another direction. There is a program in the Google Play store called "folder ...

thanks for your support.

I prefer an open source variant of an sftp server application. I tried https://f-droid.org/en/packages/org.primftpd/
and the synchronized data has the modification date of today again, so basically no solution.

Any other ideas?

I was thinking about rsync as a last resort ...

Let me know if you get stuck setting up the SFTP server.
You should add a new user and set a password.
For the Path alias this should work: "Alias:/" and then "/storage/emulated/0". You're phone may differ.

Thank you for your answers.

as @John1234 suggested, I will try the SFTP server approach.

... although not completely accurate.

Unfortunately that makes it sound as if the issue were with FreeFileSync, when it really is with Google.

And in fact syncing with Android does work correctly in some cases (or even most of the time), so it's wrong to say "MTP isn't supported" in general.

Hi,

I get good results with FFS when using SFTP to sync wirelessly to my phone.

I use a free SFTP server from Google Play.

Works better that MTP.

Give that a try.

Because MTP doesn't support it

MTP is not the issue, BUT: Google doesn't implement it properly. On some Android phones it works, on others it doesn't, but it isn't a problem with the MTP specification.


This is true! For me and many others, it has essentially evolved into an MTP issue for all ...

Hello,

I am facing the following problem.

I have synchronized some folders from my MTP device (Android Phone) with my Windows folder share via FreeFileSync on Windows.

For other reasons, it was necessary to perform a hard reset of my Android Phone.

After the hard reset, I synced the folders from ...

As suggested multiple times in this forum, instead of using the (often buggy) native MTP protocol of your phone, you can install an sftp server on your phone and sync via FFS using the SFTP protocol.

... root of my android device to my PC, however it can take upwards of 10 hours in some instances even when using usb 3.0. The main reason is that the MTP protocol does not allow for parallel transfers, however programs like "adb explorer" get around this issue with usb debugging, this has made multi ...

I understand that GVFS is ...

does anyone know a resolution to this problem? or alternitevely how i can make my pixel 8a use MTP protocol, i guess

... software can do.


Quite so. I've had chance to fiddle around a bit more today and can declare the combination of Commander One Pro for MacOS MTP access and FreeFileSync for backup/synchronisation a TOTAL SUCCESS! :)

So all of the above about rsync can be ignored as a red herring. Simply ...

Hence me searching to see whether I was missing something re. FFS not being able to access MTP devices on MacOS, and coming across this thread. I was: it turns out it can't. The documentation isn't very clear. But I guess writing a suitable ...

I have no issues performing multiple syncs to my phone, no restarts or hangs other than when the MTP connection gets "out of sync" and I have to replug the USB into the phone.
