Need to copy or sync big folders from PC

Help Fairphone 4

Hello,
Just looking for help here…
I’d like to transfer a big backup folder (40 Go/ 300.000 files) from a Windows PC to my FP4.
However when I start the copy & paste in Windows file explorer, it starts a 2-hour-long copy, then after 10-15 min it is interrupted.

I already noticed that the PC ↔ FP4 (or FP5) connection is not really stable (even with the long-life USB 3.2 cable).

So what I actually need is a tool (ideally free & open-source) that can resume the copy & paste over MTP when it gets interrupted.
Any ideas? :slight_smile:

Maybe you could install a FTP server like like this:

And then use any FTP client on your computer to push/pull the files you want to transfer.
This should give you the possibilty to resume interrupted transfers.

Or, of course, you can do it also vice versa. Use a FTP server on the computer and the client on your mobile device. E.g. you can use Filezilla on the PC .

Another way could be the following, that’s what I’m doing sometimes when handling a huge number of files:

  • copy it on a USB-C stick
  • plug it into the phone
  • use your favourite filemanager on the phone to copy the data to your device

Another option would be zipping the backup, probably chunked. 7zip can create a zip that is split into parts.

If you are able to run a python script, I recommend copyparty

I always perform large copy operations via adb push/adb pull, because MTP is the unreliable mess it is.

My backups are usually well over 100 GB and that works just fine :slightly_smiling_face:

If you’re transferring your backups regularly, Syncthing is also a great option to keep those files safely backed up without having to worry about it (runs basically everywhere).
