So I was trying to run a defrag on this computer, and then I noticed that there were tons of fragments. When I looked at the report, I saw this.

494 15 MB \WINDOWS\Installer\30697.msp
641 15 MB \WINDOWS\Installer\3827a.msp

416 15 MB \WINDOWS\Installer\35b20.msp
426 15 MB \WINDOWS\Installer\36fa9.msp
417 15 MB \WINDOWS\Installer\329ea.msp

So I was wondering, what are these .msp files? What is in this installer file anyway?

Thank you for your time =)

MSP files are known as "Windows Installer Patches" and are used to update programs in Windows. The folder I believe is just there to keep track of updates and in case you ever want to uninstall or repair the service.

Please read the following on the msp files.
Ask The Performance Team on Installer files

They are used for updates and patches. There are some in there that are orphaned due to a bad install, but very difficult to find. Recommended is to leave them.
