Problem with backup retrieval using FAST - Files and setting tansfer.

Folks I need help..else I am going to loose 60gb of my stuff here. I am using XP sp3. I used FAST to backup "my documents" folder from drive C (master) to drive D (slave) physically different, no partition. FAST created a folder USMT2.UNC. Folder shows 59.9GB size. Below is how the whole thing looks like on D drive:

Drive D:
Folder USMT2.UNC
------> Contains 1. Folder USMT2.UNC | 2. Status file | 3. IMG0001.dat = 35.6mb
--->Above folder Contains 1. Folder USMT2.UNC | 2. status file |3. IMG0001.dat = 22mb
--> Above folder Contains 1. Status file + 30 Image files each of 2GB's

I am seeing folder within folders.
I created another folder structure in D: by copying last status file and 30 image files as follows.
D: Folder named "Backup" ---->contains one Status file (last one as above) and 30 image files.

Used FAST to retrieve data back to C: from D: . FAST took two hours to do that.
Now, C: drive went from 72GB to 142GB with no size reduction in D:.

Here are the big problems:

1. I cannot find where all that 60gb went on C drive. Just can't find it anywhere.
2. C: drive under properties shows that only 2GB left out of 143GB.
3. I tried to check the size of all visible folders and files of C: it shows 72GB ========================Where in the world is everything else.

Why can't I see any of my retrieved files????

Could you please show me how to get out of this mess. It been three weekends now and I am struggling with this mess. Backup was created with XP SP3 and retrived using XP sp3....what's going on.

Thanks a ton in advance for your precious time.
