1 – Choose any file, for the testing i chose an application one, but of course you can take a .bat, a .txt a .jpeg etc..

2 – Press WIN+R or go to Start>Execute Command. When the execute command dialog apear enter ” charmap “. This will display all available characters for a specific font. Be sure you use Arial font in the drop down list.

3 – Scroll to the bottom, and find the character U+202E, it is the magic one, just select and copy it to clipboard.

4 – Now go back to your target, and right click > rename.

5 – Now you need to be precise, place your cursor just before the dot of the extension like : “DarkCoderSc|.exe” the | is the cursor ofc. Then press CTRL+V to past the magic character, now the file extension “.exe in my case” will be reverted “DarkCoderScexe.” DONT MOVE THE CURSOR, now you need to enter your new file extension reverted, like if you wan’t to put “.mp3″ you must write it like this characters by characters example : “3pm” = “mp3″.
