Clearning Program Cache?

[JHacker]

I ran Omni Disk Sweeper and it told me I had about 2 gigs of space being taken up by Program Cache. When I went in, 1.1GB of that was in Quicktime Cache (from HD trailers I'm assuming). Do I need this to be taking up memory on my computer? And how can I clear it from there without using the Omni Disk Sweeper program itself?

You can clear the QuickTime cache in the relevant System Preferences pane. You can also change its maximum capacity there.

The cache is not "taking up memory" on your computer but using
hard disk storage capacity. The next time QT launches it has access
to the data cache avoiding time consuming re-loading of recent items.
Cleaning the cache is a good idea if you are experiencing QT problems
which may be caused by corrupted cache data. Otherwise, just leave it be.

Very good point that, however with a decent internet connection I find 100MB to be more than enough. 1.1GB is massive for QuickTime cache. At least it's easy to tweak.

Weird thing is apparently Quicktime is already set to only save 100mb of information. However, when I cleared it, it freed up about 1.5GB I also used Onyx to clear my caches.
