This command displays and hides the authorizations of all the directories and files in the File Window. The authorizations determine who is allowed to access particular files or directories. The access control is based on the name you used to logon to the computer.
Authorizations are displayed as a three-letter combination for "everyone-group-owner", where "-" means no authorizations, "r" means read authorization, and "w" allows both writing and reading. For example, "-rw" would mean that the owner of the directory is allowed to read and write to the directory. Other people in the group may read the directory but others have no access at all.
See command DATABSEÞDirectory:Protect for further explanations.
