Exemptions are used by the sysop to give user's extended privilege to the system. For example, you might want to give a trustworthy user the right to remove, move, and edit descriptions of all files in the File Transfer Section. Normally users can only remove or edit the description of a file they've uploaded, but a user with the R exemption can move any file, remove any file, or edit any file description in the File Transfer Section. This ability is normally only given to sysops or co-sysops.
