I have an .EXE file that was sent to me through e-mail, but the file was changed to .EX\_ because google doesn’t like to send .EXE files.
Anyway, i copied the file to my desktop and i can’t rename it with a .exe extension. If i try changing the name by simply highlighting the name (GUI V1.ex\_) it just becomes "GUI V1.exe.ex\_ "
Same thing if I right click then click properties
i’m sure it’s simple…but how do i make it “GUI V1.exe”?

you should be able to just change it, try right clicking, rename.
