MSOCache is MicorSoft Office Cache. This is created when one installs MS Office on the sysem. This folder contains a local copy of the installation files of the MS office. This is on your Drive so as to avoid the necessity of CD drive when you want to install additional features or repair works on any installed components. Ofcourse, this is not necessary. My C drive had this folder and occupied about 600MB of space.

The point is that it can be deleted without any adverse effects on the system. In the MS Office help, they suggest that you delete it using the disk cleanup facility. I tried doing that, but it did not work for me.

So, I used explorer to locate the folder and deleted it from there. And, I have not faced any poblems till now! So there is my contribution towards the problem!
