This example handles the "Error 5 - File already open” generated when opening an already opened file
Sometimes you may have are multiple programs accessing the same data file. If LabVIEW tries opening a file that is another program already has control of (such as data backup software), you will get error 5 when trying to open the file in LabVIEW. This can cause problems if you are logging data and need all of it to be written to the file. This problem can be avoided if you use queues to write the data, and handle this specific error.
LabVIEW Full Development System 2012 or compatible
Steps to Implement or Execute Code

Run the VI
Simulate the error using the Fake Error button, When error 5 is encountered, the data will be added to the queue so no data is lost.
