I need more space on my SSD drive and I found that MSOCache is occupying 1.3 GB. I have Microsoft Office 2010 installed.
Can I safely delete MSOCache?
Short answer: no. You would most likely no longer be able to perform a repair or install additional components.
A safer option (as suggested here) is to burn the folder itself to DVD or move it to a USB drive, and change all references to it in the Windows registry.
From that page:
Way to go would be Junction Point.
For example, if you have 120 GB SSD Drive as
After this you will have entire content of
That was the answer about
NOT ENOUGH SPACE ON SSD DISK AS
The main problem here is Windows Installer, and their crappy system of caching all old installation files. Every old version of some software that once existed on your PC Windows Installer keeps in his cache folder. Stupid thing, don't you think (only because someone might Uninstall some application Windows Installer keeps all files so it could roll back to the previous state - in simplified version - believe me it's much more complicated, but accept this as is).
This wouldn't be much of problem if there aren't even bigger stupidness again from Microsoft, of course, called Windows Updates. That simply floods you with updates. And what are the Updates!? Nobody!? Updates == Installations == Bigger and bigger Windows Installation Cache.
My situation was I've installed literally base development PC with minimal Office + VS2005, VS2008, VS2010 - That is I must have. I had this on XP machine primary disk with 120 GB just fine and plenty of drive space left with all updates installed (~100GB). But Windows 7 == 30 GB free space (Imagine my face when I saw that). I know windows 7 is little bigger but not 70GB bigger.
... and now 2 hours later I am back to 70 GB ;) HOW you ask me!?
Simply performed same thing as above for following folders:
Commands are very similar:
Notice only to stop Windows Update, Trusted Installer, and Windows Installer services before moving those folders, run them after if you wish or simply restart (10 seconds for a reboot on SSD).
I have reclaimed back 40GB of (100% uselessly taken space, since I will never uninstall anything I use). Haven't broken any windows rules, since they use for
Still poking around what else I could move to (Magnetic) HDD drive...
One thing to notice you will have
The Local Install Source (Msocache) feature is installed so that you do not have to insert the CD during the following Setup operations:
You can use the Windows Cleanup Wizard to remove the Msocache folder. To do this, follow the steps in the related Microsoft article.
Warning: Never delete the MSOCACHE folder by using Microsoft Windows Explorer.
The best way to prevent this folder from being placed on your drive in the first place, is by selecting the Delete installation files check-box during the installation of Office.
From this thread :
I have a 64GB SSD and LOADS of programs. I regularly move space gluttons to a HDD. Many programs now use 500MB-1.3GB for garbage like page borders and all sorts of small image files.
Don't screw with the registry. Sooner or later it'll bite you in the butt bigtime. Create a junction, as mentioned in SoLaR's answer.
HOWEVER -- SOME CAVEATS.
Very similar to previous answers - the twist is I moved
Yes, you can delete the MSOCache folder, if when you install MS Office, you select the option to "Run all from My Computer".
Check that option under Microsoft Office, then check Not Available for the components you don't need. I've installed only Excel (tons faster than LibreCalc), Word and PowerPoint, then I've renamed MSOCache to "junk.MSOCache.deleteme". I don't plan to install any other Office components.
So far, no problems. Haven't tried installing any Office updates because I don't need any security patches (the only Office files I use are my own), but if you want the updates, install them first and delete/rename MSOCache after.
