Then we use the rename MS DOS Commands to do so. For example, if a file named inpage is deleted computer.inp, it will be backed up with the same name but its extension will be computer.inpB01. Now change this extension.
Way – as soon as ren computer.inpB01, computer.inp is entered, The backup file will be converted into the original file. Now we can open this file in that program. The program that contains this file.
In this way, the Extention of any backup file can be changed to the original file. But it is necessary to replace the Extention of the backup file with the extension of the program that the file is.

And we want that we do not need to write these commandos daily. To do this, create a batch file of these commands. Whose extension name is bat.
Method – C: > copy con LAB.bat Time Date Dir ^ Z Enter after pressing Ctrl + Z. The batch file will be generated. Now to run it, just write the name of the file with which the batch file is created at C prompt. Results will be displayed as soon as you enter.

The number of letters you will write by pressing the space in computer language is called a word.
C: > DIR Z *. *
This will show all files starting with Z. This way if we forgot the name and the extension name is So instead of the name, Star (*) then Dot (.) Then Extension Name.
Like – C: > dir *. Now with the Extention, all the files will be visible.
