&nbsp;Hi,

I'm looking to send an email from my Automise project when the free drive space falls below 5% of the total available. What I have so far follows. I'm looking to use the results of the&nbsp;Get Logical Disk Information action but currently can only put all of the results into one variable rather than the size and the free space into separate ones for comparison.&nbsp;

Any help is greatly appreciated

Steph

Action Description: 5.1 Get Logical Disk Information [C:]
