Xcacls Overview


This command-line tool sets all file-system security options that are accessible in Windows Explorer. XcAcls does this by displaying and modifying the access control lists (ACLs) of files.

XcAcls is especially useful in unattended installations of Microsoft Windows XP. Using this tool, you can set the initial access rights for folders in which the operating system resides. When you distribute software to servers or workstations, XcAcls also offers one-step protection against deletion of directories or files by users.
