Two programs cannot register the same extension.  Any program can use any file, but if Program B registers .txt after Program A, it will overwrite the registry.

So how this works is if I try to open a .txt file, the kernel will then check the registry to see which program is registered to open .txt files. And if there is no program available will it give me options to open it?

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

I think it would be like that, from his post, or throw an error "No Program Set to Open This"

You open the file, and it checks the registry.  If it is registered, KnightOS runs that program with the name of the file passed in the arguments.  If not, it lets the user browse to a program to open it with, or choose from common programs.

As many as you like.  If you want to fill all of ROM with your filename, you can go for it.

Lol, so can it go across sector boundaries, or is that just an issue with TIOS?

So I'm guessing you aren't going to think about using magic bits?

Ah, magic numbers.  I suspectd that's what you were talking about.  And magic numbers hasn't been a good system for years and years.  And it's totally incompatible with every other OS.  I want cross-compatability with Linux, Windows, Mac, etc.

Well most operating systems that use it also use extensions for cross compatibility, but it would be helpful for files without extensions. But anywho, it's your choice :)
