Nextcloud Desktop sync deletes / removes all your custom folder icons

PowerQuest · November 26, 2025, 3:12am

Well pretty much as it says.
I been looking for a way to fix this.

in the past you could get around it by removing the shell extension (msiexec /passive /i Nextcloud-x.y.z-x64.msi NO_SHELL_EXTENSIONS="1") when in installing but not so anymore…

Nextcloud seems to have done it even more hardcore in removing your own custom folder icons…

Anyone here that know a way to fix thus “huge” issue please?

Thanks in advance!

Kind regards

Not sure if that is really related since you have this extra option to disable the extensions. If you know, when it was working and when it starts breaking, you can open a different topic on the bug tracker.
