The whole "change the file type of the character files and getting Easter eggs" thing and how it affects the game maybe?

[Mannequia]

I know that changing the file types of the character files can reveal hidden Easter eggs but how does the game react to having the file type of the character file changed? Like how If you delete Monika's character file and start a new game and Sayori's character file is still there Sayori will break into hysterics because she is now sentient because whoever is club president is aware that they're in a game and Sayori is not prepared to handle all that info because it's the beginning of the game so she commits suicide and I think deletes everyone I don't remember if that part also happens or if that's a different situation but either way yeah would the game count having a character file be a png file or ogg file for instance as that character just being fully deleted or would nothing happen or would something new happen? I'm kinda at the end of the game with Monika and the space room and I wanna see what else she has to say so I won't be progressing to the actual end for awhile so I can't really try it myself right now. and even if I do get to doing that before anyone responds to this, I'm not 100% sure on how you change file types or what files types even work with my computer outside the usual jpeg and png and mp3 and all that, but either way I'm happy to see everyone's findings if anyone even sees this like ever and yeah okay thank you goodbye

Monika has something like 61 topics and certainly interesting. On changing file types, that's the usual Windows way. (Monika says, please don't, it hurts.) Fortunately I was using my linux machine and the text editor passing over the file ikon reads and displays the header so you see what kind it is.

But then it get even more curious. One example: Sayori's is an ogg audio file. But it sounds like noise. Someone did a spectrogram of that, looked like a QR code, fiddled awhile and actually scanned it with his phone - and got a URL to a real website. :-)

Just duplicate the character files on some other directory. Change their extension there, done.
Search online any list of audio and image file extension to see all posible combinations.
