Vista - Extremely slow zip file extraction

I am using vista without sp1. It takes about 6 minutes to extract a 900kb
file. This is consistant with any zip file I try to extract. Another
example was a file that was 1.7mb which took almost 30 minutes. I do not use
any 3rd party programs currently for dealing with zipped files and this was a
clean vista install. I thought maybe there was a coflict with the file being
virus scanned as it was extracting. I was using AVG but I have it disabled
so that it doesn't launch at startup. Please note that is not the most
current version of AVG designed for vista. I recall this being a problem
even before I installed AVG antivirus however this may still be some part of
the issue. I wanted to check for other suggestions before I completely
dumped my virus program. Thanks for any help you can provide.

Hi William,

Avast is another great free antivirus program.

avast! antivirus Home Edition, anti-spyware & anti-rootkit for Windows

However, you might give the free program 7-Zip a try to see if you like it better than Vista's built-in Zip handler. I use it and think it is much better. Plus, it supports more file types to.

7-Zip

Hope this helps,
Shawn

Have you tried WinZip or WinRar (you can use trial versions) to unzip
the file to compare times versus Vista?? This may give you a clue...

Hi, I have seen the same issue in Vista SP1 release notes marked as fixed.
So I am pretty sure the zip extraction will work much faster after upgrading
to SP1. The SP1 should be out very soon for the rest of the world - I think
I've heared somewhere that MS said it will be out at mid april (it is
already out for lucky 5 languages - english, spanish, french - I've forgot
other two).

P.S. do not dump your antivirus (just wait a week ot two for SP1) - I'am
also using AVG free version - it is nice program.

SP1 doesn't fix this problem. And using another utility only gives a slight improvement. Disabling UAC and Remote Differential Compression makes no difference. The problem seems to extend beyond zip files and affects all file operations. Even opening a folder can be painfullly slow (especially when clicking on the folder in the folders tree).

Interestingly, my son is running the same setup as me and doesn't experience any of these problems, which leads me to believe it's some kind of configuration issue. Has anyone experienced this problem and actually solved it?

I'm always curious whether Microsoft makes any effort at all to fix these kinds of fundamental problems with their OS. They seem content to just ignore them and let the hackers figure it out.

Microsoft will not be able to cure configuration problems because they have
no control over what each user runs or does to the computer.

Has folder access always been slow? If so, there could be a problem with
your hard drive.

The Vista unzip facility is known to be slow, but there are workarounds..

Personally, I always use a 3rd party utility. This is a good one..
