Then everyone who starts using the Nextcloud Desktop Client must be informed that this is a centralized backup-sync solution where the server is the master.
It cannot be that when you do your first Desktop client sync, that certain folders get removed from your local harddrive. NEVER remove data that has not been synced yet. Or ask the user what he wants to do with those folders.
But do not just remove them.
Please read this again to understand your users:
- Unchecked folders will be REMOVED from your file system
- https://github.com/owncloud/client/issues/2502
Well, you have the developers opinion and 90 % of the users expected behavior. What is more important for a good and solid product? JM2C.
