I have an MS Project 2010 file, with about 500 tasks. It exploded at some point, to a size on my disk of nearly 40Mb. As an experiment, I made a copy of the file (still large, using Save as immediately upon opening). I then deleted EVERY SINGLE TASK. File only went down in size a couple of K.
What in the heck is going on? I see in threads all over the net where folks have a problem with "bloat" but I don't see anything from MS on how to address it. I am unable to share my file via email, etc, any longer.
Note: I have no graphics in the file, and, as I noted, above, at one point, I had a 40Mb file with NO tasks at all.
