Is there any software for opening files with the same extension in different software depending on the file's signature?
For example, a file with extension .pcb and file signature PCB FILE 4 should be opened in one program, while a file with extension .pcb and file signature 00 FF should be opened in an entirely different program.
I made my own solution a while ago, which I will post as an answer, but it's annoying and clunky to use, and maybe there's some obscure general-purpose dedicated compiled solution out there that works better.
