One of the best Millenium Edition Features is the compressed folder.
When you use a conventional zip program, you will always have to
wait for several minutes for the program to 'unzip' the file that
you want to open. The Millenium Edition of Windows has the solution
for it with its Compressed Folder, folders which can manage your
zipped files as any zip application would do, and unzip the file
at a stunning fast speed, as you would do in any folders in Windows
Explorer.
By default, this Windows Feature is not installed and you will
have to activate it from the add/remove programs in the Control
Panel.
Check(tick) Compressed Folders and click on OK. Windows will install
the program and update its settings and may or may not ask you to
reboot your machine. Do it.
After having installed it, all your compressed folders will have
the same (zipfolder) icon. You will be able to browse in them as
fast as in a normal folder.
