About this tag
The CACLS command-line tool is used to view and modify discretionary access control lists (DACLs) on files and folders in Windows. Discussions on WindowsForum.com cover several practical issues with CACLS. Users report that CACLS silently aborts when encountering the "System Volume Information" folder, which is a known limitation. Others ask how to list files owned by a specific user pattern using CACLS or ICACLS. A common question is the difference between CACLS for file permissions and "net share" for folder sharing. Several threads describe accidentally denying Full Control to system drives via the GUI, leaving the system inaccessible. In such cases, CACLS itself may fail with "Access is denied," even from an administrator account, making recovery difficult. These topics highlight CACLS's role in permission management and its limitations in recovery scenarios.

    Windows 7 How to unset administrator deny permission?
