Windows 7 | Delete Offline File Cache CSC Folder

After carrying out a domain migration on a PC the “offline files cache” still retains a local cache for the previous domain.

Within “Offline Files” (Control Panel) there is an option to “Delete temporary files” but this does not remove the “All offline files” cache located in the “C:\Windows\CSC” folder

The workaround to fully remove these files (and start a new offline sync) is to add the “FormatDatabase” registry entry which forces deletion.

This command will add the registry entry. After which reboot the system and all offline files will be removed:

reg add HKLM\SYSTEM\CurrentControlSet\services\CSC\Parameters /v FormatDatabase /t REG_DWORD /d 1
