Am I in a Dilbert Cartoon? Is there a way to purge? Why is File sizes changing for almost identical Parts up to 3 time bigger?

I feel like I am in a Dillard Cartoon every now and again.

So I am drawing some simple captive fatteners and I am getting file sizes from 240 KB to 757 KB for almost the same part except dimensions for different sizes.  The files do have design tables, but only one "Display States.

Most were from copy as files and they only have one feature.

I am thinking not a big deal, except one file is 3.1 times as big for almost the same part. So maybe there is a way of purging like AutoCad.  And as people use parts it will change the assembly sizes a lot.

Also the first one I drew had a file size of about 600KB then I did a save as and it got smaller then added another 30 sided array and the part got smaller again. So the part with 2 features was smaller than the part with only one feature?

Doing a root cause analysis of this? 5 Whys? etc.

1  there is a command I am missing like purge.

2  There is a purge command missing that needs to be added.

3  Windows is messing up with the file sizes. (a software programmer conspiracy!)

4  SolidWorks programmer don't care about file sizes.(ie, the mechanical/electrical can make bigger hard drives)

5  Windows is inefficient at saving files.

6  So one possible root cause seem to be the Software Programmers/Scientist at Solidworks having a little fun with the Mechanical Engineers. If that is the case, Ha Ha now please fix memory saving.

7  Be like Dilbert and except the ridicules

Does you have a reason? please post.
