How to stop different users from creating folder with same name?

Hi,

First of all I did not find appropriate category (like sysadmin) to put this question to.

We are facing problem as users are creating folders with the same name. It is becoming difficult to manage those. Difficult to find appropriate folder when a change has to be done and implemented across the user community.

Is there a way folder name can be enforced to be unique?

Thanks.
