Prevent End Users from Adding Folders within Document Libraries

You probably know by now that I am not the biggest fan of using folders within SharePoint document libraries. I wrote an article about this a while ago. Although I have become a bit milder over the past year, mainly due to a great presentation by Bobby Chang, I still do not recommend folders to my customers (for the reasons I stated in my previous article). I suggest this really easy “trick” to avoid end users from adding folders—just disable the New Folder command in each document library they use. Log in with appropriate permissions and follow these instructions:

1. Navigate to the document library where you want to disable folders.
2. In the ribbon, click Library.
3. Click Library Settings.
4. Click Advanced Settings and then choose No for the following question:

Unfortunately, users with full control permissions to the document library can undo these changes. Teach these users why they should not change this setting. Conclusion? The folder change may not be guaranteed, but it is definitely helpful. – See more at: http://www.itunity.com/article/prevent-endusers-adding-folders-753#sthash.yRVngrdN.dpuf
