Hi Edwin,
Syncthing only creates the marker .stfolder and any subdirectories during the sync process. The “root” folders configured for syncing must be created by the user via the usual OS tools and be readable and/or writable by the user Syncthing is to be run under.
I highly recommend reviewing the documentation before diving in with configuring Syncthing because it’ll avoid a lot of potential hurdles. In particular, start with the “Introduction” section:
- Introduction — Syncthing documentation
- Getting Started — Syncthing documentation
- An Intro to the GUI — Syncthing documentation
I see that you also had an earlier post under a different title and category that’s related to this post:
On your Ubuntu Linux computer, is “root” running Syncthing? If not, you’ll need to assign the proper permissions for whoever the user is on the /var/syncthing/f2vab-tafsf directory if that’s where you want to store files and directories to be synced to/from your ODROID SBC/tablet (Android or regular Linux?).
Screenshots of the Syncthing web GUI – with devices and folder panels expanded so that we can see the settings – will be very useful (and likely attract more helpful responses).
