Windows 7 where has my memory gone?

Nobody answered the thread so I continued on my own.

I went to allexperts.com and posed my question.

In less than an hour I received the solution to my problem.

I downloaded the free Treesizer programfrom Jam.com. Treesizer showed all files and the amount of memory they used.

I found almost all of the missing memory was in the db files of my Seagate Replica program.

I Googled Seagate db files and found that others had experienced the same problem and simply deleted the earliest db files.

I deleted all db files and suddenly my C drive memory was restored to normal. Seagate had been storing all restore information.

I now have to regularly dump db files.

I hope this helps someone.
