Exceptionally large Installer folder

[Ryan Spehle]

My computer is running low on memory so I started searching my computer for
the usage. My Installer Folder is 39.2 GB. I have a 120 GB harddrive
(Explorer states 111GB) and this is a good portion of the harddrive. From
what I gather most of what is in the folder are updates to Microsoft Office
and other programs. Is there a way to clean this folder up without
corrupting any programs? Please advise.

First - what is your "My Installer Folder" path?

Might I suggest... CCleaner.

If you are comfortable with the stability of your system, you can delete the
uninstall files for the patches that Windows XP has installed...

You can run Disk Cleanup - built into Windows XP - to erase all but your
latest restore point and cleanup even more "loose files"..

You can turn off hibernation if it is on and you don't use it..

When you hibernate your computer, Windows saves the contents of the system's
memory to the hiberfil.sys file. As a result, the size of the hiberfil.sys
file will always equal the amount of physical memory in your system. If you
don't use the hibernate feature and want to recapture the space that Windows
uses for the hiberfil.sys file, perform the following steps:

- Start the Control Panel Power Options applet (go to Start, Settings,
Control Panel, and click Power Options).
- Select the Hibernate tab, clear the "Enable hibernation" check box, then
click OK; although you might think otherwise, selecting Never under the
"System hibernates" option on the Power Schemes tab doesn't delete the
hiberfil.sys file.
- Windows will remove the "System hibernates" option from the Power Schemes
tab and delete the hiberfil.sys file.

You can control how much space your System Restore can use...

1. Click Start, right-click My Computer, and then click Properties.
2. Click the System Restore tab.
3. Highlight one of your drives (or C: if you only have one) and click on
the "Settings" button.
4. Change the percentage of disk space you wish to allow.. I suggest moving
the slider until you have just about 1GB (1024MB or close to that...)
5. Click OK.. Then Click OK again.

You can control how much space your Temporary Internet Files can utilize...

Empty your Temporary Internet Files and shrink the size it stores to a
size between 64MB and 128MB..

- Open ONE copy of Internet Explorer.
- Select TOOLS -> Internet Options.
- Under the General tab in the "Temporary Internet Files" section, do the
following:
- Click on "Delete Cookies" (click OK)
- Click on "Settings" and change the "Amount of disk space to use:" to
something between 64MB and 128MB. (It may be MUCH larger right
now.)
- Click OK.
- Click on "Delete Files" and select to "Delete all offline contents"
(the checkbox) and click OK. (If you had a LOT, this could take 2-10
minutes or more.)
- Once it is done, click OK, close Internet Explorer, re-open Internet
Explorer.

You can use an application that scans your system for log files and
temporary files and use that to get rid of those:

Ccleaner (Free!)
http://www.ccleaner.com/

Those can help you visually discover where all the space is being used.

In the end - a standard Windows XP installation with all sorts of extras
will not likely be above about 4.5GB to 9GB in size. If you have more space
than that (likely do on a modern machine) and most of it seems to be used -
likely you need to copy *your stuff* off and/or find a better way to manage
it.

My computer is running low on memory

The word "memory" is used to refer to RAM. You apparently mean "hard
drive space," not memory. If you call it "memory," you run the risk of
confusing those who try to help you, and therefore getting wrong, and
possibly dangerous, advice.

so I started searching my computer for
the usage. My Installer Folder is 39.2 GB. I have a 120 GB harddrive
(Explorer states 111GB)

Explorer is correct. Your drive is actually *not* 120GB.

All hard drive manufacturers define 1GB as 1,000,000,000 bytes, while
the rest of the computer world, including Windows, defines it as 2 to
the 30th power (1,073,741,824) bytes. So a 120 billion byte drive is
actually a little under 112GB. Some people point out that the official
international standard defines the "G" of GB as one billion, not
1,073,741,824. Correct though they are, using the binary value of GB
is so well established in the computer world that I consider using the
decimal value of a billion to be deceptive marketing.

and this is a good portion of the harddrive. From
what I gather most of what is in the folder are updates to Microsoft Office
and other programs. Is there a way to clean this folder up without
corrupting any programs? Please advise.

Read Shenan Stanley's reply for good advice.

 

[Ryan Spehle]

Thank you for the tips. I was able to clean up some of my hardrive space (a
little over a 1 GB) but I was not able to clean the patch files from my
"Installer" folder. The path you requested is.... "C:\WINDOWS\Installer".
This folder is still at 39.2GB.

It is strange that your "C:\Windows\Installer" folder would be that size. I

you have (unless you happen to have AutoDesk, 3D Studio, Office 2007 and
2003, full Adobe Creative Suite, MatLab, SAS, SPSS, Wisual Studio and
various other little plugins and programs installed needed to support a

Run it and scan the offending folder - is there a particular sub-folder

If so - which one is it?

You don't want to go deleting stuff from this folder - things can go bad
*and* you would lose the ability to uninstall some things.

There is something you could try - but as with anything - make sure your
backups are up to date first (your files/folders/product
keys/email/contacts/Internet favorites/etc) - because things can still
always go bad if the gnat lands on the butterfly's wing in Alaska on a

[R. McCarty]

Sometimes I run into XP machines that have these excessive size
\Installer folders. It's something of a pain to match the .msi/.msp
modules to an entry in the Registry ( keyword = PackageName ).
Usually you can locate the "Culprit" by it's file size. The largest
size you'll normally encounter is around ~250 Megabytes. When
you notice excessive size of the \Installers you'll likely find modules
that exceed 3 Gigabytes.

It's VERY dangerous to make changes in the \Installer folder. It
can easily break things like Office Updates and other apps. Also
you can NOT redirect \Installers like other Windows or User data
folders.

I was updating volunteer workstations and some servers last week and had
a server fail multiple times when trying to install MSO 2007 sp2. Then
I received a message stating disk space was low on C: (don't install
apps there). I found that each time SP2 tried to install, it would
throw almost 400 meg of files into the installer folder, and when it
failed, they remained. So each attempt added 400 meg. I finally
realized it and removed all the files comparing time stamps.

I'm sure this is happening to many users without their knowledge.

Sorry for the delayed response. I thank you again for your time. I did
download the jdiskreport as suggested. There is not a large subfolder
however 98% of everything is a ".msp" file extension all located in the
"C:\Windows\Installer" folder. I am unable to create a backup or a System
Restore point. The computer will not allow it, therefore, I do not feel
comfortable running the "msizap.exe" command that you had suggested. If this
would solve the issue with "good confidence", I will take the chance. Please
advise.
Also, I am not receiving a "low memory" message. I apologize for the
confusion by using incorrect terminology.

Why will your computer not allow you to backup?

System Restore <> Backup of your stuff.

When I say backup - I mean connecting some external media to that computer
(whether that is writing to CD/DVD, external USB drive or memory stick or a
network share on another computer or a network attached storage device...)
and somehow copying at least your stuff ("My Documents", "Desktop",
"Favorites", "Outlook Express Email", "Outlook Email" and any executables
you use to install applications along with their associated product
key/serial numbers, etc...) to that external media. That could be
drag-and-drop, that could be using the built-in backup program, that could
be using a third party backup program or that could be using a program like
Symantec Ghost or Acronis TrueImage or something similar to make an image of
the entire hard disk drive. This is something you should be able to do if
you have zero space free on your main drive - as long as it boots (and in
some of the cases mentioned - whether it boots to WIndows or not.)

The command I gave is fairly safe to perform. It would be safer (as would
daily use of the computer) if you had solid backups of at least your stuff
as well as the installation media for everything else.

http://thebackroomtech.com/2009/01/...aller-data-files-to-increase-free-disk-space/

Want to be even more safe? Use that external media and simply *move*
everything in that folder (C:\Windows\Installer) to the external media.
Reboot. Now do the other cleanups (not the msizap) to your machine. Once
you have cleaned up/defragged and made a solid backup of your system to
external media (should be able to now if your problem was somehow a lack of
free space) - you have a couple of choices.

(1) just keep that moved folder contents on the external drive and continue
using the computer until you feel confident enough to delete the stuff.
and/or
(2) *Copy* it back (copy, not move) and then run the MSIZAP command to see
what happens. You have a backup of the folder contents - you should have a
backup of the system state and your stuff.

Thank you very much for your time on this subject. Using "msizap.exe" seemed

create a backup or a System Restore point. The computer will not
allow it, therefore, I do not feel comfortable running the
"msizap.exe" command that you had suggested. If this would solve
the issue with "good confidence", I will take the chance. Please
advise.

Also, I am not receiving a "low memory" message. I apologize for
the confusion by using incorrect terminology.

Why will your computer not allow you to backup?

System Restore <> Backup of your stuff.

When I say backup - I mean connecting some external media to that
computer (whether that is writing to CD/DVD, external USB drive or
memory stick or a network share on another computer or a network
attached storage device...) and somehow copying at least your stuff
("My Documents", "Desktop", "Favorites", "Outlook Express Email",
"Outlook Email" and any executables you use to install applications
along with their associated product key/serial numbers, etc...) to
that external media. That could be drag-and-drop, that could be
using the built-in backup program, that could be using a third
party backup program or that could be using a program like Symantec
Ghost or Acronis TrueImage or something similar to make an image of
the entire hard disk drive. This is something you should be able
to do if you have zero space free on your main drive - as long as
it boots (and in some of the cases mentioned - whether it boots to
WIndows or not.)

The command I gave is fairly safe to perform. It would be safer
(as would daily use of the computer) if you had solid backups of at
least your stuff as well as the installation media for everything
else.

Want to be even more safe? Use that external media and simply
*move* everything in that folder (C:\Windows\Installer) to the
external media. Reboot. Now do the other cleanups (not the msizap)
to your machine. Once you have cleaned up/defragged and made a
solid backup of your system to external media (should be able to
now if your problem was somehow a lack of free space) - you have a
couple of choices.

(1) just keep that moved folder contents on the external drive and
continue using the computer until you feel confident enough to
delete the stuff. and/or
(2) *Copy* it back (copy, not move) and then run the MSIZAP command
to see what happens. You have a backup of the folder contents -
you should have a backup of the system state and your stuff.

Thank you very much for your time on this subject. Using
"msizap.exe" seemed to do the trick and everything seems to work
fine as of yet. I went from
39.2GB to 818MB in that folder. I really appreciate this.

Glad that helped and thank you for returning to let everyone know!
