WebDAV sync - what is the meaning of remote database icon?

I am syncing multiple DT databases over WebDAV.

When I connect to the WebDAV server, I noticed 2 different icons on the left side of the remote database names that I want to import to a Mac:

  • A round blue nautilus shell
  • A square blue DT sign

Do these logo indicate something?

It’s the logo of the app which updated the database in the sync store the last time.

I.e. DTTG or DT3? I use both.

The round one is DEVONthink 3.
The square one is DEVONthink To Go

Check, makes sense in my case.
