System exec rmdir doesn't work

[Sirin]

You're right. The OpenG source code does do a much better job of deleting the files. It is still CPU intensive, but, that is probably the way it will have to be to delete a whole directory like this. Thank you all for your help. (Although, I'm still curious why the system exec and rmdir command didn't work.)

Thanks for showing me OpenG by the way. It looks to be a really comprehensive set of tools.

Yes, it is strange.

Did you capture the standard output and standard error for some clues?

Have you also tried e.g. "del /F /S /Q".

I put probes off of those inputs when I was executing the system exec VI, thinking there might be some sort of error message as well, but they both came back as empty. One thing I didn't do was connect up the error out from the system exec VI to a generic error handler; so it is possible that the VI was returning some sort of LabVIEW error.

System Exec does execute applications and command files like *.exe and *.com. However some commonly used command like dir or rmdir are not executable command files but commands internal to the command interpreter which is cmd.exe. To execute these internal commands you have to invoke cmd.exe first with System Exec.
In that case, the string you pass to System Exec is "cmd.exe /C rmdir [path]".

Thanks for the information.
