There was a hidden folder called "MSOCache". In the folder, there were
tons of cab files. Total size of the MSO Cache was about 300 MB. What is
MSO Cache?
Can I delete it without affecting WinXP Pro? Roman

The MSOCache folder contains the Office Setup files, so that to repair/reinstall an Office component, you don't have to insert the Office CD-ROM everytime. If the MSOCache folder is deleted, you'll need to use the Office CD-ROM to repair or reinstall Office components. In addition to the links supplied by Shenan, these may help also:

OK - I read the info in the Google links. The problem is I have Office 2000
Pro upgraded to Office XP Pro so why do I have an MSOCACHE folder? I'm not
running Office 2003. And, Disk Cleanup DID NOT remove the folder.

Well.. It appears for Office XP installation also creates the MSOCache folder. It's evident from the following Office article:

http://office.microsoft.com/en-us/orkXP/HA011362521033.aspx

<excerpt>
The automatic repair feature of Office XP is dependent on the availability of the MSI cached to the user's computer. If the MSI file is deleted, is corrupt, was moved, or is the wrong version for the installed edition of Office, Windows Installer fails to update or correct any faults with the installation. Various error messages appear when this file is not available.

Important To avoid problems with the MSI file, do not delete folders from a hard drive that have a name similer to MSOCACHE. Most likely, the MSI file needed by Office XP and Windows Installer is cached as a hidden file within this folder.

Disk Cleanup does NOT remove the folder by default. You need to place a checkmark near "Office Setup files" in Disk Cleanup window, in order to clear the MSOCache folder.

I have a question about the MSOCache folder. On my computer, I have a single
hard drive, partitioned into C, D. E and F partitions. Why is the MSOCache
folder put on D partition, and is there a way during the Office setup, to
specify where it should be placed?

I don't remember a way to specify that during installation, or even
to specify *whether* it is done. But after installation you can move
the cache and change the appropriate registry key to point to the new
location.

Local Install Source (Msocache):
http://support.microsoft.com/kb/825933

<excerpt>

Note The MSOCACHE folder is not always located on the disk drive with the most free space. If your computer has an NTFS drive with at least 1.5 GB of free space, the MSOCACHE folder will be located on that NTFS drive.

</excerpt>

and from that article:

<excerpt>

Move LIS Cache folder to a new drive location
A tool has been developed that lets you change the location of your Local Install Source cache folder after it has been established by a product install. To download the Local Installation Source Tool, visit the following Microsoft Web site:

You can control the Local Install Source Tool settings and location by using the Setup.ini file, or from a command line. For more information about how to control the Local Install Source Tool settings and location, see the Setup.htm file on the Office 2003 installation CD.
