I am now managing Windows Server 2003 originally setup by someone else.
What I noticed is that even though file compression is not turned on at the drive level (when I go to drive Properties "Compress drive to save disk space" is unchecked) a lot of files are still compressed on the disk seemingly at random. For example in "C:\Windows" folder about half of the files are compressed (appear blue in Windows Explorer and have "AC" attributes) and another half is not compressed.
What I want to do is to disable compression because we have more then enough disc space and compression just slows things down.
Is there some other option (other than disc properties) where file compression is controlled? Can this attribute be changed by some process? I just don't think someone went through thousands of files on the disc and hand-picked them for compression.
Whatever the reason - how would I go about disabling it completely? Using ATTRIB.EXE on the drive root folder recursively?
