Hi,
I work with five different Nextclouds - three for different business reasons and two private ones.
By default, all five sync folders in Windows Explorer are called “Nextcloud” - a bit hard to distinguish, to say the least 
.
Renaming by changing the registry expression DisplayNameResource (as already recommended elsewhere) works - unfortunately only until the next restart (at least of the Nextcloud desktop app).
Obviously there will be a way to fix such a fundamental problem and distinguish multiple Nextcloud synchronisations - but I’m too stupid to find it 
! Can anyone help me?
Thanks, Stephan
