How can I make a personal extension for a file so that it works like exe?

Question

Windows

For example, I want to make a file that will be called name.qnahabr
and that at startup it will run as the same regular exe
Is this even possible?

Answer 1

from under the administrator in the command line

assoc .qnahabr=myexefile
ftype myexefile="%1" %*

also, extensions *.pif *.exe *.com are absolutely equivalent.
*.scr - almost, the /S key is added there.

c:\>assoc .exe
.exe=exefile

c:\>ftype exefile
exefile="%1" %*

c:\>assoc .pif
.pif=piffile

c:\>ftype piffile
piffile="%1" %*

c:\>assoc .scr
.scr=scrfile

c:\>ftype scrfile
scrfile="%1" /S

Answer 2

Yes, it's possible. It is enough to register the extension in the system and assign a handler program to it. You open pictures somehow, don't you?
So google "how to register your extension". You can also assign an icon there.

Answer 3

that is, transfer a certain number of bytes to the site page

You do not need to send bytes, but send a regular POST request with data.
