File Compression is a feature available as part of the operating system.
Your reference to UT2004 threw me as I have never before encountered the
software. Using Google I now appreciate what you are referring to.
UT2004 incorporates a file compression option, which is separate from
the Microsoft feature. The UT2004 feature is more like WinZip software.
The file is compressed so that it can be transported from one location
to another in a compressed state. There is more about UT2004 compression
in the link which follows:

Returning to the Microsoft feature. Automatic file compression can be
carried out using Disk CleanUp.
Compress Old Files - Windows can compress files that you have not used
recently. Compressing files saves disk space, but you can still use the
files. No files are deleted. Because files are compressed at different
rates, the displayed amount of disk space that you will gain is
approximate. An Options button permits you to specify the number of days
to wait before Disk Cleanup compresses an unused file.

When using Disk CleanUp many users are frustrated by the length of time
time it takes to load Disk CleanUp because it computes an approximate
saving in disk space. This frustration is often voiced in these
newsgroups. It is clear that Disk CleanUp is selective as to which files
it compresses both as to type and age. I do not know of any list as to
which types are iincluded for compression and which excluded. I would
imagine there is a list somewhere. As a file is only compressed after
the expiry of XX days you will find, as you have noticed, folders
containing some files compressed and others not compressed. You can
right click on the folder and manually compress the contents of the
folder regardless of the age of the file at any time.
