[How to]Change extension for multiple files at a time (Simple DOS trick)

Here this is a cool stuff which i tried and quite interesting and can be done simple using DOS format.

[For Ex]This can be helpful especially if you have movie file parts say some 7 parts of zip files or .SVN file. You got to change these file extension to .rar format so as to extract into a single file.

Also change any formats to any formats for multiple files since this takes just a second rather changing extension for all files take a huge amount of time.

Follow these tricks:

Just keep all the movie files or zip files in a separate folder Say C:\mines

Now move to DOS command prompt by Start>Run>Cmd

Go to folder where you have those zip or movie files using “cd pathname” Ex cd mines

Also you can check the contents to verify that you are in the destined folder using DIR command that displays all the contents of zip or movie files

After that Type or Copy this command “rename *.* *.rar” [ without QUOTES ] into DOS prompt. Check the above Screen-shot.

Replace rar with any extensions say .txt, .mov, .avi …..Just to view the change

Check out the destined folder..it replaces all the files to the format you mentioned in DOS prmpt..[Here .rar ]
