1. Use of Undelete utilities.
Use the Undelete facilities in case you accidentally delete your files.
There are two Undelete facilities depending on the operating system you are using.
a. MS-DOS 6.0 Undelete facility:
To undelete at the DOS prompt, change to the drive & directory whose files were deleted, then type, e.g.,

C:\>UNDELETE
A list of all deleted files will be displayed with the first letter missing. Type in the first letter and the file will be recovered.
b. Norton utilities & PC Tools:
Norton utilities & PC Tools also have an undelete facility, which is similar to the DOS Undelete facility.
c. Windows Recycle Bin:
The Recycle Bin temporarily stores all deleted files & can be used to recover your files.
1. Double-click the Recycle Bin on the desktop.
2. Click on the files you want to undelete.
3. Click on File, choose Restore.
The Recycle Bin will restore all selected files to their original folders and disks.
NB: If you delete a file accidentally, don’t copy any files or install any applications to the disk that contains the deleted file. If you write anything to the disk, you might destroy parts of the deleted file, making it unrecoverable.

2. Use of Unformat utilities.
MS-DOS 6.0 has an Unformat facility which can be used to recover information stored on disks that have been accidentally formatted.

3. Use of Backups.
All data must be backed up periodically either on diskettes, tapes or CDs so that in case of any accidental loss, the backed up copy can be used to recover the data.
