I don’t know what the current situation is with group folders but this is my experience using them.
I set them up under NC13x and all seemed fine, I reported in another post that when I upgraded to 14.0 the files I had in NC were deleted. The files and directories were deleted from all workstations that had NC clients actively syncing. I thought this was deleting all files and directories but now I think it was only the ones in Group Folders.
I reverted back to NC 13 using SiteGrounds Restore function through CPanel and restored the whole NC system from before the upgrade and recovered everything but I had to do some manual things to get the files back on the clients.
Since then I upgraded again, this time to to 14.03. In the process, All group folders and the files in them were deleted from the NC Database on the server and all workstations across the internet - about 7 computers were affected. Files and directories GONE.
Our NC servers are installed on SiteGround under our domain names - two separate NC Systems.
The files themselves were not deleted from the NextcloudData directories so we were able to restore them. Apparently only pointers to them but they were deleted from the client workstations.
It is apparent that something in the Group Folders application is not connecting when upgrading causing this problem.
The only work around I know is to stop syncing before upgrading- renaming the workstation directories ( if you don’t, the directories and files will be deleted when you turn syncing back on) And then rebuilding the group folders with the web interface.
From reading the many posts on this subject it appears problems with group folders has been around a while and should not be listed as a stable release. I have decided to abandon them until I see this is seriously addressed. I think the problem is that Groupfolders application is removed when you upgrade because it is no longer on our servers and I did not remove it from either of the two sites.
My suggestion is to not install group folders on anything but a testing platform and start with an older version of NC and do some upgrades and watch what happens on your clients.
Thank you, I hope this helps others. If I am doing something wrong, I have no Idea what it is, I use the NC Updater or SiteGrounds Softacalculous to do the upgrade. So If you have something to share to say what is going on I would like to hear from you,
… Another Note: I did not see any messages about upgradding the group folder or any other addon application when I started the upgrade. Should I have?
UPDATE: Sorry for the long and perhaps unnecessary post. After taking another look I wento the apps page and saw group folders was disabled. After re-enabling and upgrading from there all is back. .
I apparently forgot about that when I read the documentation… Yes I am a Man and I read the instructions anyway
