I was working on this new puzzle for quite some time now. Unfortunately, I locked the file and now I don't remember the password... :(

Here's a snapshot. I think I might have left some clues for cracking it. But I am lost..Not sure what was it..

Transcript of file name


Can you help me find my password?


As already observed in comments, start by recognizing the file type. And then utilize .

    $\begingroup$ @Rubio it's just, you see, there are these three things out of quite a lot. These things are called 'keys'. They are found on keyboards, commonly associated with laptops and computers. These particular keys are called 'ctrl', 'c' and 'v'. They all do different things but together can form magic. You see, 'ctrl' and 'c' are amazing friends who note down everything they see. 'ctrl' and 'v', are also friends but they love writing things really, really fast. Together, they can duplicate text. It makes things very easy. Don't worry if you don't understand, it is very complicated. :P $\endgroup$ Apr 11, 2017 at 20:18

    $\begingroup$ @BeastlyGerbil Where's the ctrl key? There doesn't seem to be any ctrl key! All I see is ⌘, ⌥, ... $\endgroup$

    $\begingroup$ On the face of it, there doesn't seem much more to this than "Here's some ciphertext: WFBEBOCLECHKLBPM. Now decipher it!" which is plainly unreasonable. So perhaps there's some other clue hidden somewhere. $\endgroup$
