How can a copy of a document be one tenth the size?

I made a copy of a 237 MB document and its size is 28 MB. I wonder what accounts for the significant size reduction.

when making a copy of a document it purges all the history, I assume that is the reason.

@jon_woellhaf The reason @_ÐAVE_ gave is correct.  A document is not just the current state of things, it is also the full history of how it got to the current point in time.  When you copy a workspace to create a new document, there is very little history in that copy.
