# Disk Security Metadata File

The disk security metadata file is named `DiskSecurity.xml`. The file defines security rules for all disks on a Plesk-managed server except for the `%plesk_vhosts%` folder where hosted domain folders are located. The file is located in the `%plesk_dir%etc\DiskSecurity` directory, where `%plesk_dir%` is the Windows environment variable designating the Plesk installation directory.

Note

Exercise caution when changing disk security rules by editing the `DiskSecurity.xml` file. Follow recommendations in the section Customizing Disk Security to avoid potential problems in administering disk security policy in Plesk.
