All executable from my computer can be opened with 7Zip but my mini game.exe cannot be open with 7Zip Why?
My game.exe is not Portable Executable(PE)?
What kind of file is this file which cannot be opened with 7zip?
By The Way, I attached the file here.

I forgot to tell you why:
Because I want to attach into EXE few files

I don't really understand what you're trying to do, but that extracted and ran fine.

Executable files aren't supposed to be opened with 7zip, which is a file packing compressor/de-compressor. If you want to make an executable that you can open with 7zip, then you need to create an archive.

But as I said before, you aren't supposed to be able to open exe files you compile with 7zip or anything like it.
