What are the best folders to choose for compressing?

Sorry to hijack this thread but your answer poses another question.

I deliberately turned off compressing by right clicking my hard
drive>Properties and unticking/(unchecking) "Compress drive to save disk
space".

I also unticked this option in Disk Cleanup.

However, when I look in my Windows folder (show hidden files and
folders), all the service pack uninstall files are blue.

Is this a feature that is automatically downloaded with the service pack
files?

No they are just compressed and the Blue inicates as such.

"Compress drive to save disk space". This not the same as file
compression. You do not want to compress the drive.

The compression referred to in Disk CleanUp is file compression.
Unchecking the option does not decompress those files compressed
previously.

Thanks, I understand that.

What I wanted to know is, as I have not selected either option to
compress (Drive or Disk Cleanup) and have not done so for years, why do
the uninstall files still show up in blue. Is it because they are
downloaded as compressed files? I assume that SP3 has overwritten files
that may have been compressed by Disk Cleanup many moons ago.

Thanks everybody, but I'm looking for specific folders that are good candidates for compression,
like:

C:\WINDOWS\Downloaded Installations
C:\WINDOWS\inf
C:\WINDOWS\Installer
C:\WINDOWS\system32\dllcache

I have not got a complete answer to your question. What I have
discovered is that there is more than one factor coming into play.

Some files are compressed because they have not been accessed within the
time setting within Disk CleanUp. On my computer I have it set to 50
days. However, I have some folders where the contents are compressed
and created within the last 50 days so these have not been compressed as
a result of running Disk CleanUp. The files are Uninstall files created
when an update is installed using Windows Update. Originally these files
were not compressed but some years ago I decided to compress these
files. This can be done by placing the cursor on the folder, right
clicking and selecting Properties, Advanced, and checking the box before
"Compress Contents to Save disk space". What has me puzzled is that it
is some time since I manually used file compression and I have folders
created last week which are compressed and are not themselves contents
of a compressed folder.

I have no more time to research further so I must leave it there.

At a guess, the program that installed the fixes, and thus created the
uninstall folder, realised that the chances of your needing those files
was minuscule, that if you *did* need them, it would only take a few
seconds extra to uncompress them, and in the meantime you'd welcome the
extra free space on your drive. I know I do. I routinely compress all
of my backup files.

Yes, I'm beginning to think that they are downloaded as compressed
files.

What's downloaded doesn't end up in the uninstall folders; it is what
gets replaced that ends up there (so you can put it back if you uninstall).

However, it would also make sense if the downloaded files were
compressed, as that might save some network bandwidth. I'd be just a
little concerned, however, that an additional uncompress stage would be
one more place where things could go wrong, and when dealing with
operating system executable files, you really need to eliminate any
possibility of error.

Mind, the compress/uncompress algorithms must be pretty well debugged by
now... imagine the mayhem if there were any errors (shudder).

Actually, unless you tell it not to, windows will compress seldom used
files anyway, including the uninstall files. Mine are all compressed
along with several other files; and windows did it, not me.

"Actually, unless you tell it not to, windows will compress seldom used

That's not quite correct. The uninstall folders for Microsoft updates
are downloaded as compressed archives. Windows XP only compresses seldom
used files if you ask the Disk Cleanup Wizard to do that.

Hmm, Didn't know that about the updates uninstalls being compressed when
they were created; could very well be.

You're right about Disk Cleanup having an option to compress files; but
somehow there is/are another way/s it occurs. I've noted it happening
multiple times that previously uncompressed files became compressed but
I can't back that up with anything to prove it; it's just a memory since
it didn't matter to me other than as a "huh" when it happened.

I'm not arguing with you; you are right in what you say. As a matter of
curiousity though I thought I'd post this to see if it triggered anyone
else's memory. I'm sure it wasn't just pipe dreams<g>. Then again...
