Not sure what happened, all my user programs got migrated to a (timestamp_backup) backup directory. All backup files have a .inp file extension. In the backup directory, there are a couple of directories containing .xml files listing the path of my user programs and a status file showing the migration status. Now my PC only has the window 7 OS and the user data. All the user installed programs are gone. How can I undo the “migration”? Pls help.
