What Are ACLs?
Access to files and directories (folders) in UBFS is controlled through access control lists (ACLs), which describe the access granted to a list of users and groups. Groups are lists of users. These lists are created by system administrators. Because you are the owner of all subdirectories under your personal disk area, you have full access control over them. You can view and modify ACL settings with the DCECP ACL command interface on UBUnix.
