Binary File Storage on CVS - Space Questions

[Witchman]

Consider this situation: I have a 16MB binary file stored on a CVS server I add 2MB of data to this file after checking it out. I commit my changes. Using viewcvs, I download both version 1.1 and 1.2   Since CVS (from what I understand) can’t really look at the contents of a binary file, how does it store the revision?  I assumed that it would overwrite the 1.1 with 1.2, but I was able to download both.  Looking at the directory of my repository, I only see the file that is the size of 1.2.  How is this?   Thanks!   Michael Lawrie Member, Technical Staff Northrop Grumman - TASC www.tasc.com
