Windows Explorer is the file management application in Windows. Windows Explorer can be used to navigate your hard drive and display the contents of the folders and subfolders you use to organize your files on your hard drive. Windows Explorer is automatically launched any time you open a folder in Windows XP.
The MIRROR command is used to save information that can be used later for file recovery using the UNDELETE and UNFORMAT commands. MIRROR creates a duplicate or MIRROR of this important information in case the original information becomes unreadable. (New with DOS Version 5.) For each drive you specify, MIRROR creates a read-only file named MIRROR.FIL on the disk`s root directory.
