Hi there,
just out of curiosity: 
I have a rather complex TestSystem (>600SubVIs) with a huge main (joblist-driven kind of state machine).
Just checked VI_properties.Memory_Usage and found this (attached).:
FP Objects:    253,2K
BD Objects:    2125,5K
Code:             480,9K
Data:                  163,8K
Total:                  ~3023,5K
Total VI Size On Disk: 3985,3K
Is there any explanation for this ~1MB extra size on disk?
