So there I am, happily computing on my normal office desktop, when I notice that the C drive is, like, totally full. Wait a minute, I think to myself, didn't I have at least a third of that drive empty when last I looked?

Also, Google Earth, my favorite place on the whole damn web, weren't working right.

After trying to figure out a way of finding out where all this memory had gone, I decided to back-up and delete my two biggest folders: work and photos / videos.

Lo, I've got my globe back.

For a bit.

Then I get notified that my G-E cache is all kinds of full. I follow the steps to purge it. Cool. It works. Check the volume on the main drive. This cleared a huge amount of memory off the drive, like 40%. Wow.

So I look it up, google style, and I find this http://productforums.google.com/forum/#!topic/earth/vJcVK2M9g7U%5B51-75-false%5D, which documents similar experiences, both before and after the update.

I am running ver. 7.1.1.1580. Win 7. 64.

I've a very extensive places list. Like the garage, it could use a good cleaning. But would that have anything to do with it?

Something I'm going to watch, now that I know what is going on.

Anyone else have this experience?

Is there a way of quickly finding whatever folder is bloated?

Is there a way of viewing volume statistics over time, to detect a spike in memory use as a graph?

UPDATE: Been browsing logs. Norton tells me that two days ago, while Google Earth was idle, it up and wrote 305,971 MB to my drive.
