Or, how you can use the Office Remove Hidden Data tool to compress your Word documents.
Recently I've been spending a lot of time editing Word documents with other people. This typically requires a final pass to… harmonize… the different format styles that people use. After the latest session of removing visible gunk, I got to wondering whether the new Remove Hidden Data tool could get rid of the physical gunk. A quick experiment with five different Word documents from various sources shows that yes, yes it can:
Fair warning: the tool happily consumed >10 minutes of CPU time on a 3 GHz Xeon for #5, and it marks the resulting file as read-only. But a compression ratio of up to 6-to-1 is not to be sniffed at!

Update: There's a new version of the tool available, which promises “substantially increased” performance (via Roberdan)
