*.dwg file size curiosity.
(OP)
Hi, all.
This is not an earth-shattering deeply technical problem, but it has the potential to keep me awake at night. I am hoping that someone can give me a logical explanation for something I observed just now.
I opened a drawing - call it "Rev1.dwg". Win Explorer tells me it is 270 kB.
Without altering anything on it, I immediately saved it as "Rev2.dwg" via the "Save as" button. At that stage Win Explorer told me it was now 272 kB.
I reopened "Rev2.dwg" and immediately saved it as "Rev2.dwg" again (overwriting the existing file). Win Explorer now tells me it is 274 kB.
ie it appears that every time I go through the "Save as" routine, I add 2 kB to the file.
Why would that be??

Thank you all for your help. I don't use ACAD very often, and had been presuming that I was doing something stupid. (That still remains another possibility, of course).
It just seems to me that adding 2kB each new "save as" is a bit excessive. I will try the purge command - that sounds very promising.
Having started my computing days well before DOS, today's gross use of memory still offends me. I recall doing useful stuff (eg analysis of a general 2D arch under variable local loads) with a machine that had a total of 120 bytes of addressable memory. We had to give that up when we couldn't get the rubber drive bands any more.
