Problem with floppy disk

I am green from that I start.
I have a problem with a program that needs to verify whether it is on a floppy disk or on a computer or it can be something to check?

Moved to Ask a Pro.

Not too familiar with floppy disks and the like, but I think

fs.getDir(shell.getRunningProgram())

Will do the trick. Not sure, but that's how I'd determine the directory to a program on the computer.

Use fs.getDrive instead.
It will return "hdd" if the file is located locally on the computer, or "rom" if it's in rom.
If your file is running on a disk then it will return the side where your drive is located.

local fDrive = fs.getDrive(shell.getRunningProgram())
if fDrive == "hdd" or fDrive == "rom" then
  print("File is running from hdd")
else
  print("File is on a floppy")
end
