How Do I Monitor Available Storage Space on a LabVIEW Real-Time Controller?

Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I want to log data to my LabVIEW Real-Time controller (Compact FieldPoint, CompactRIO, Compact Vision System, Real-Time PXI, etc). How do I check how much storage capacity I have available to save information?

Solution:
The amount of hard disk or non-volatile storage available on a LabVIEW Real-Time controller depends on several factors including the installed software and existing files on the controller. It is possible to check the available memory on a real-time target externally or programmatically within the real-time VI.

Externally

Open Measurement and Automation Explorer (MAX). You can do this by selecting Start»Programs»National Instruments»Measurement & Automation.
Expand Remote Systems in the Configuration window.
Select your real-time controller.
In the main window, select the System Settings tab. This tab includes the total disk space and the amount of free space on the disk.

Programmatically

Use the Get Volume Info function when targeted to the controller. This function can be found on the Advanced File Functions palette (Programming»File I/O»Advanced File Functions»Get Volume Info). See the LabVIEW Real-Time Module Help for assistance with targeting VI's to a real-time controller.
