I'd like to verify that a particular folder exists on the local drive

[Arrington]

I have an application that gathers data and writes it to a text file on the local hard drive. Yesterday we found that the folder in which the text file is to be written was not present on the drive, but there was no indication to the user that there had been any problem with writing the file. What's the best way to have LabVIEW (6.1) verify that a given folder exists? (I have a couple of ideas I'm working with, but there's got to be something better.) I'd like to have a dialog box appear telling the user to stop testing if that folder does not exist.
Thank you very much,

Use File/Dir Info (Functoins->File I/O->Advanced) to check if it exists. See example.

Try to make a directory-listing of the folder, this should yield 2+
enties i fthe folder exists and 0 or an error if it doesn't
exist.

Thanks! That's a lot easier than what I had prepared.
