I heard dat *.exe files and ntfs filesystem is d proprietary of microsoft?
Wont d use of dem cause ny copyright infringement issues?
Should v create r own executable extension 4 use in r OS?
Should v program our own compiler (or linker) to output files of our custom extension
Is FAT a better choice than NTFS in any way or should v create r own filesystem?

Thanks a lot.

Hello,

The EXE and NTFS specifications are copyrighted, but implementations of those specifications are not. This allows NTFS and EXE to be supported on 3rd party operating systems without legal issues. This also allows other standards, such as EFI, to use EXE without problems.

However -- for a "real" OS you might conclude that having your own executable image format to be the best option. However you can certainly use ELF or PE as well without problems.
