Questionable .bip file sizes?? File size bloat?

[theAVator]

Right now I'm working on a pretty large project (mostly animations and images to use in the animation). I have my "source" .bip file that I was working with, but had been producing many crashes and out of memory errors. So I took the file and slimmed it down considerably (mostly deleting parts and deleting scene sets, etc) and then saved it as a new file.

The issue I see is that there isn't a drastic reduction in file size or RAM usage with the slimmed down file and this doesn't seem like it should be the case. Does KS bloat the files in any way? like saving extra info that may or may not be used/wanted, etc?

Below are the numbers I have for each file. Does this seem odd to anyone else based on these numbers?
Source file:
Default scene set: Triangles 138,123,228     NURBS 1,914,590
Scene Set 2: Triangles 138,123,228     NURBS 1,942,987
Scene Set 3: Triangles 138,123,228     NURBS 1,942,987
Scene Set 4: Triangles 138,123,228     NURBS 1,942,987
Scene Set 5: Triangles 12,183,274     NURBS 387,146
Total File Size: 13.4 GB
Typical RAM Usage: 28-33 GB

Reduced file:
Default scene set: Triangles 11,004,897     NURBS 203,374
Scene Set 2: Triangles 2,739,697     NURBS 66,306
Total File Size: 9.68 GB
Typical RAM Usage: 17-20 GB

I guess to me it seems like a 3.72GB reduction seems pretty small considering the drastic difference in numbers. I guess I would've expected at least a 50% reduction or more possibly. Am I off my rocker or is this correct and I just need carry on?

Virtual RAM: i think around 32GB

Scene sets don't duplicate geometry. They only create instances which don't increase the file size by much. So most of the reduction is coming from deleting actual geometry from the "default" scene set.

Are you messing with me? lol

I opened up my reduced file, added 5 turntable animations to it, hit save, and now the file size is 1.11GB. 

So I guess I was correct, there should have been a much more drastic reduction in file size. But how come it didn't reduce until I actually added something to the file/default scene set? That sort of circles back to the question of bloat: does it retain stuff in the file until it actually has to re-write the file data or... ??

hmm - that is interesting. Will have to check.

This issue is fixed in 7. You will see the reduction in file size upon initial save.

Awesome! Thanks!

Now just to acquire KS7. haha
