You use the Ximage.exe tool to mount a Microsoft Windows Imaging Format (WIM) file for read and write access in Windows Vista. Then, you try to delete this file by using Microsoft Windows Explorer. However, you cannot delete this file, and you receive the following error message:

Cannot delete filename: Access is denied. Make sure the disk is not full or write-protected and that the file is currently not in use.

Note: When this problem occurs, you can still mount or modify a WIM file by using the Ximage.exe tool.
