The cmd route should work. Done it many times doing like .mp4 to .m4b. You go I to cmd (command). Type the following: cd “FILE-PATH” (without quotations). Hit enter. Then type: ren *.file-type *.file-type Example would look like: ren *.jpg *.PNG This woukd be renamed the files all from jpg to png

I don’t feel too strongly one way or the other. It’s alright. You can make up your own mind about it. Anime fans tend to circle jerk a lot of things. If you like it, cool. If you don’t, cool.

Fucking absurd.
