You can tell it to compress or not compress files or directories (Right-click|Properties|General|Advanced...).

From: joe on 25 Feb 2010 10:30 Thanks Bob and Tim. I was not aware of this and both of those situations apply to me. i.e. There are files which are infrequently accessed and I use 'disk cleanup' all the time. You learn something new every day :-) "Bob I" <birelan(a)yahoo.com> wrote in message news:uj1GrOitKHA.4220(a)TK2MSFTNGP05.phx.gbl... > Yes if you run disk cleanup (see below) > http://en.wikipedia.org/wiki/Disk_Cleanup > > joe wrote: > >> Does the OS do this automatically and if so under what circumstances ? >> >> "Tim Slattery" <Slattery_T(a)bls.gov> wrote in message >> news:6eoao5h110aceg6vu58t7iv4uioro6m9m4(a)4ax.com... >> >>>"Twayne" <nobody(a)spamcop.net> wrote: >>> >>> >>>>IN XP's case, zip = compressed = zipped ... . >>>> >>>>A zipped file is compressed, but a compressed file is not necessarily >>>>zipped >>>>as there are other methods for compressing file sizes.

If you check, you'll find the blue is zipped/compressed files and green is encrypted files. You can set/adjust these from the Properties menu for each file you right click Properties and choose Advanced for. Try it and see; You'll find that: Blue *IS* zip compression for XP NTFS drives. Compress or encrypt a file and see what color it changes to. The color indicator can also be turned off so they all display in black is so desired. In the future, please be more sure of your responses before becoming emphatic.
