creating folders

[fkesmail]

How do i check for a pre-existing folder. what i am trying to do is to create a vi that would create folder but once created not overwrite it, just skip the creation part.

[RavensFan]

There is a function called "Check if file or folder exists" in the File I/O  --> Advanced File Functions palette.

I dont see that option. I am using Labview 8.0.

Also if my runs 1000 times, how do i stop the folder creating and repition 1000 times, because the vi for creating folder looks up the directory and finds a replica and stops.

i found it, but my second question still remains a mystery

On the Structures palette is a case statement. You might want to consider wiring the output of the Check if File or Folder Exists to a case statement and placing the code that creates a folder inside the case statement.

This is pretty elemental programming. Have you seen the learning LabVIEW basics resources here?

Well i got the problem solved. i just had to search for .txt string instead of looking for folder because the folder lookup vi was not working the way i had the setup. and also using the folder option was over-writing all the files within. so search file option did the trick.

Thanks
