Modifiing Nextcloud files via filebrowser in android

Hello,

I use the newest version on android and I have nextcloud app installed.

when I sync, the files are stored under /android/media/com.nextcloud.client/…

what happens when I delete or I add files there directly with the browser.
Can those changes be synchronised or do I always have to use the app for this kinda operation, so its synchronised?

thanks

you can alter excisting files there and resync with the app

you cannot ( as far as i know ) put new files there
they will not be synced unless uploaded trought the app.

hope this is clear enough.

I use foldersync for sycronisation, here i can choose which folders i want to sync how with my nextcloud instance and under what conditions.
