vi memory usage vs size on disk

[BVSmith]

I have a VI whose "Memory Usage" property shows Total memory usage of 157.9k, but total VI size on disk of 1353.2k.

Why would that be?

32-bit LabVIEW 2016 f2 patch

64-bit Windows 7

Hi Smith,

lots of images on the front panel?

For more detailed analysis you should attach your VI!

As Gerd says, pictures would explain it. The Total Size is the sum of code node and objects, not total memory size.

Personally i'm more surprised that my empty test diagram has 2,7k block objects and 4,3k front panel objects, but i suspect that front panel picture results in some hidden code.

Ah, sorry, no pictures at all.  See attached VI.

I did figure it out, though.  There is a reference to an IMAQ image as an input and one as an output.

When I deleted those, the disk usage went down to 33k.

Why would they take up disk space at all?
