Delete .EXE on disk while executing

In FORTRAN, can an .EXE file delete its own image on disk at the time of execution?

Fortran, the language, has no concept of file deletion nor of "EXE". What you're asking tends to be a property of the operating system, not a particular language or compiler.

I tried the experiment with CVF on Windows, and it did not work. Indeed, the documentation says that you cannot delete a file that is currently being accessed - which you can see if you try this in Windows Explorer.

Thanks, Steve. I also tried some tricks like attempting to kill the executable on disk from a thread, etc. It didn't work. My specific problem is cleaning up after installation / uninstallation. I can do everything except deleting installer/uninstaller at the end of the respective process. How do other people solve this problem in Windows? Is there always a small leftover? After your comments, I should ask my question in a different way: Are there Windows means of erasing an executable from a hard drive while executable is still working or can executable leave a request ("will") to be deleted immediately after execution? If such means exist can they be accessed from FORTRAN?

Most installers use a "driver" program that unpacks files used for installation, does the install, then cleans up the unpacked files. The driver program itself (usually setup.exe) is typically not automatically deleted. If you use a standard installer creation tool, this is handled for you automatically.

I'd be annoyed if an installer deleted itself after installation.

Windows does have a mechanism for doing something close to what you want - you can specify arbitrary commands to be executed on the next reboot. You've seen this at work when you uninstall a product and it tells you a reboot is needed. See here for more information.

I tried. It works for me. The case is closed.

Thanks a lot, Steve.
