If a user is deleted and they are the owner/main recipient of a system Filedrop, then that system Filedrop is also deleted. I would suggest one of the two: Modify the "Confirm action" warning to include any information about Filedrops the user might own. Current warning: Proposed warning message (or something similar): Ideally, another option would be to provide a screen or popup window to allow you to change the owner of the system Filedrop before the user is deleted.
