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.
Backup provides you with a tree view of the files and folders that you have backed up, which you can use to select the files and folders that you want to restore. You can use this tree view the same way you use Windows Explorer to open drives and folders and select files. Choose where to restore the backed-up files.
