I have an 8 MB .mpp file being shared by 15 or 20 people that periodically bumps up in size (as viewed in the SharePoint 2010 version history list) by ~4 MB. There are currently 83 versions; a base, 3 majors, and the rest are minor versions.
The first time it happened the person editing the file reported no bulk additions, only edits were to dates already in the plan. Response time between task double click and task information window appearing was about a minute. At end of that
edit session size grew from 13.3 MB to 18 MB.
The bump up happened again today (two weeks later) when a user did some block moves inside the file, he says no new content copied in, but did manually create some new tasks. The size in the version history is shown to be 25.5 MB, up from 20.8 MB.
I'm becoming a little concerned. This is environment is behind a corporate firewall so while it's possible that there is a virus at work here, I'd be surprised.
Any ideas what might be causing this docyument to grow like that? Is there an "Accept Revisions" function that will rebaseline the file and keep this from getting even larger?
