Given a Dropbox folder which has many hidden deleted files/folder, currently I have to delete them manually sub folder by sub folder.
Is it possible to delete them all quickly?
To test your problem,
ALL folders/sub-folders within disappeared. I did all this from within the web interface.
If someone else can verify this behaviour, I'd be much obliged.
This ought to make your task easier.
Keyboard shortcut doesn't work. Most easy way: click sort all files by "Kind" column -> select range of all deleted files (click first, hold shift + click last in list). Then you can permanently delete them. If you don't select continuous range of files it doesn't show the "permanently delete" option.
