What is Xcalcls.vbs

There is an updated version of the Extended Change Access Control List tool (Xcacls.exe) that is available as a Microsoft Visual Basic script (Xcacls.vbs) from Microsoft. This step-by-step article describes how to use the Xcacls.vbs script to modify and to view NTFS file system permissions for files or for folders. You can use Xcacls.vbs from the command line to set all the file system security options that are accessible in Microsoft Windows Explorer.
