Hi,

I'm trying to free up some space on my Windows 10 laptop and. There's also a lot of.msp files in the C: Windows Installer directory. For in Windows but most of the tools you need to manage storage are built into the OS. From research this folder can be safely deleted, however you MUST NOT delete the top level “Installer” folder “C: WINDOWS Installer” (only the sub-folders inside it) A quick method for deleting this directory is. Dec 06, 2016  Morning All, I've been wrestling with a problem with our installer for a couple of days. It is a Basic MSI project, and for every build we change the Package Code, leaving the product code and version untouched (thus making this a 'Small Update' in installer parlance, I believe).

I would like to inform you that, it is not recommended to delete Windows Installer Patch Files. The Windows Installer Cache, located in c:windowsinstaller folder, is used to store important files for applications installed using the Windows Installer technology and should not be deleted. If the installer cache has been compromised, you may not immediately see problems until you perform an action such as uninstall, repair, or update on a product.

When a product is installed using Windows Installer critical files are stored in the Windows Installer Cache (default is C:WindowsInstaller). These files are required for uninstalling and updating applications. Missing files cannot be copied between machines since they are unique.

If you do not have enough space on c: drive, you may try the below suggestions:
a. Move the download folder to another drive.
b. Empty recycle bin
c. Uninstall the applications that you no more use.
d. Perform disk cleanup, refer the below links.

(Applies to windows 10 as well)

Hope it helps. Revert to us with the results, will be glad to assist you.

Thank you.

This folder is taking up nearly a GB of my C partition. Is it possible to just delete it?

I think it should be safe to remove the files, provided you're able to download them again in future if they're needed or if you have access to your original install disks. I had something similar on my computer, I just deleted it and install things from the original disk every time it asks me now. Inconvenient, yeah; but I don't often install stuff and it's a lot better than having a whole ton of space on my hard drive wasted.

Heath Stewart's The Patch Cache and Freeing Space on MSDN blogs explains in detail. An excerpt:

[.] cause the Windows Installer service to cache any of the original files being replaced into the baseline cache. [.] It is this baseline cache that consumes a lot of drive space on the system drive after installing [.] The baseline cache facilitates patch uninstall by storing the original files so that they can be copied back to the target locations.

[.] by removing the baseline cache for a product, future repair, patch install, and patch uninstall scenarios may require your original installation media. If you have the drive space it is recommended that you keep the baseline caches available.

You could also try the MSIZAP utility from Microsoft. It has a 'safe' option, 'G'.

What I do for this folder is revisit it every now and then and only delete packages in there that are at least six months old. This way, if there's a bad patch that I need to roll back, I can usually still do it.

Is it possible? Yes.Should you? Probably not, if you don't have to. Windows Installer keeps those files around because it think they're needed if you ever have to install another patch on top of them (or uninstall those particular patches).

If in doubt, you can always go safer way: simply compress entire Installer map! Right click on the Installer map (or just $PatchCache$ map) and choose Properties. On General tab, click Advanced button. Finally, check Compress folders to save disk space. If asked, choose an option to compress all subfolders and files.

This way you can gain up to 30% of free space (or in your case, nearly 300MB), and you keep everything in case you'll need this stuff later on. And system speed and response wont be affected much since system rarely accesses this map.

You can apply this tactic to several other non-essential system maps, thus recovering lots of free space on your drive!

Instead use MKLINK to junction the folder to an alternate drive if you have space

• on drive D: create sub folder named C

• cut and paste folder Installer to subfolder C-Windows located on drive D: Subtitle indonesia sherlock holmes season 3 episode 1.

• run CMD

• type: CD C:Windows

• type: MKLINK /J Installer D:C-WindowsInstaller

• type: EXIT

The solution is to use the command from Start → Run → cmd:

Warning: This will not affect the Installer folder. All content msi files created there will remain until the program is uninstalled. $PatchCache$ can grow up to GB of size which takes a lot of my hard disk space.

This command will delete $PatchCache$, and after you finish, run

… to see if the folder is still there.

You can also use

Delete Windows Installer Patch Files

which deletes all files in the temporary folder, which are created by installing software.
