When i go into my computer it used 2 have 4 folders now it only has 3 the shared and 2 other users one is missing but it is still on the c drive what do i need 2 do

Look for it in c:\documents and settings\your_user_name\

If it's not in there it's not on your hard drive

Its on my hard drive and i thought i had noted that it was when I posted this question but does any one know why it is not showing up under the my computer?

You question is unclear.
What are you saying? When you click "My Computer", you're not seeing "My Documents" in the list but only the "Shared Folder"?

If that's the case, My Documents doesn't show up under mine either.

There are 3 users on my computer. Therfor the would be the "shared documents" and three others, but the "Shared" is there and two others are there
