Count ALL Files in a Directory and Sub-directories Recursively Using LabVIEW

[neffk]

Overview

This VI will count ALL files in a specified folder and all sub-folders recursively.

Description

This VI makes use of recursion. A recursive VI must be reentrant (see LabVIEW help on reentrant). The VI creates a reference to itself and then calls Open VI Reference to open a new VI of itself. The new VI is passed with the subfolder of the parent folder and process is repeated for the subfolder (as if it were the parent folder).

Once all subfolders are traversed the sum of the subfolders count and the parent folders are added together to give a final count.

Beware of using this program on a large system directory. A new VI will be spawned fo reach subfolder in your folder tree and this could cause memory errors.

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Specify the folder path.
2. Run the VI and check the VI numbers on the front panel indicator.
