Hi Tom, I'm not sure how to disable this feature, but you could try doing
the following:
1. Remove the compression attribute on the top-level folders where user docs
are stored on your server, selecting the option to apply the change to files
and subfolders. This will decompress all the folder trees on your server
(make sure your disk volume has enough room for everything first).
2. Notify users they should not compress docs in their home folders stored
on the server.
3. Enforce this policy within your company.
