Description
This example covers how you check if a particular file is open on your computer in LabVIEW. You also can use this functionality to share a single file between multiple LabVIEW users or an .exe.
How to Use
Most of the File I/O VIs and Functions will give you an error if the file in question is open when the VI executes.
To check if a file is open, you can use a File I/O function, such as Open/Create/Replace File, and evaluate the error code to see if the file is open. For example, Open/Create/Replace File gives error code 5 if you attempt to open a file that is already open.
See the attached VI for an example.
