It will create the backup of all the important directories such as user profiles, Windows folder, Program Files directory, and other important locations from your old version of Windows. These backups are then stored in Windows.old and $Windows.~BT folders, which can later be used to recover data that could not be transferred to the newer version. Moreover, you could also delete these folders to create additional storage space if you feel the data is useless.
