TNAS Mobile and android

[Krbuc]

Hey,
I am wondering how to automatically sync android folders? For example I was using OneDrive on android and I'd open and edit a word doc, save it and it was just synced to OneDrive again. I want to do the same thing but with my NAS. I put a file on the NAS, opened it with TNAS app and it opened in the word app but I could only save to device, not the NAS. I'm assuming there's no way to easily map to the NAS folder in android like a windows machine does.
So was thinking I can just have a local, android folder with documents I may want to edit or work on. Then have that folder sync automatically to the NAS. I was able to do it for my phone photos but I couldn't find an option to sync non photo folders.

Any suggestions or a different app maybe?

Thanks!

Hello, currently, we do not possess the function of automatic synchronous. You can manually back up the files in your mobile phone to TNAS via TNAS Mobile.

Is there another app which will?
