Bug description

In low disk space situations, Nextcloud Desktop on MacOS displays an Error when trying to sync files.

To remmediate this situation, I unchecked a few folders to regain disk space.

However, it seems that PRIOR to removing the folders, some checks happen / it wants to sync the pending files.

I am thus ending in a deadlock, where I cannot clean up my Nextcloud Sync folder.

Steps to reproduce

Have very little disk space left, i.e. 200MiB
Have files pending to download, i.e. Fotos from mobile phone
Get an error, see picture
Uncheck folders you don't want to sync
Observe that the folders are NOT removed, sync error prevails.

Expected behavior

Unsync folders prior to syncing new files. This might give more free disk space.

I'd try with the following workaround:

make sure you have no files pending for upload (if you have some, backup them first to a local folder outside sync);
remove the current account in the client and close the client app;
delete the Nextcloud folder, you may also want to clean your trash bin;
reopen the app, recreate the account and start with nothing or only a few small folders checked;
Add/remove folders later as needed.

This should get you out of that loop.

By the way, I'd suggest you set a meaningful title to this issue ;-)

Thanks. I was able to get out of that loop already.

Also, perhaps the extensive configuration options of rsync can serve as a template to an improved behaviour.
