Syncthing is a tool for syncing files and folders between computers without the need for a central server or host. I've been using it to replace what I used to use NextCloud and/or OwnCloud for.

Somewhat like .gitignore with a slightly different syntax; .stignore tells Syncthing which files you don't want to keep synced on that particular machine.

A quirk seems to be that the * needs to be last?

In .gitignore I often start by ignoring ever thing, then adding the few things I want to include:

*
images/
index.html

But to do the same in .stignore I have to:

images/
index.html
*

On Android I use what is called 'Syncthing-Fork' on F-Droid. It adds some useful features over the official Android version.

• f-droid.org/packages/com.github.catfriend1.syncthingandroid

I've had this off-again on-again problem where a particular folder won't sync., showing the error message 'Error (folder marker missing)'. Once this was solved just because syncthing-fork was out of date, but today I had to install Simple File Manager Pro from F-Droid (as they recommend), and then go to the synced. folder and manually create the file .stfolder. This is supposed to happen automatically on upgrading.
