have the followinf tools:
Emu8086 version 2.57
and flatassembler latest version.

1)In flatassembler the compiled files end in EXE.
On Emu8086 they end in COM.
If i want to create an OS are these extensions usable?
I mean if i create it in Com/EXE Format and make a OS Loader,will it work?
Thanks in advance!

If you plan on using established file formats, you will have to do a lot of work first. The easiest way to just get something that can boot is to use "org 7C00h". This allows you to assemble a boot sector. Read up on writting boot sectors and take a look at Bochs or something similar.
