When minimum disk space is reached folder stops from syncing completely.
It would be better if folder tries to sync deleted files to free some space.
For ex. I have two PCs A and B and a synced Folder. PC-A has 100Gb and PC-B has 1TB. I work on a PC-B and make some large files in the Folder. PC-A tries to sync and stops because out of space. Then I delete large files on PC-B and expect PC-A to continue syncing, but it still shows out of space and does not sync. So I have to manually log in to PC-A and restart syncing or adjust space treshold or delete some files.
