I've read a few threads about this, but unfortunately none with an actual answer. I need a group of users to be able to modify/create/append files in a folder but NOT to create new folders. Unfortunately, for some wonderful reason, MS has decided to have "create folders / append data" on the same check box, so I haven't been able to have it both ways. The workaround is to work on the file and save it as a different name, but this is a huge hassle for the users.. The current way I have it setup is for the group to have full control on the "share" tab, and to have everything but "create folders / append data" on the advanced tab.. No dice. Anyone have any other ideas?
