Once a rollup archive has been decompressed, a manifest file is accessible in the root-directory of the extracted files. In the RU5 for the SP1 (KB982812) this file is called “dynamicsax2009-kb982812-sp1-manifest.xml”. So far so good. Unfortunately this manifest file can be very large and is over 1GB for the RU. This because the file contains not only the changes, but also all dependencies, with makes this file so verbose.
The TransformTool is very simple tool and might help you working with these data by transforming the original manifest data into a much less verbose xml-file:
