Windows 7 - Problem moving files to shared folder

Its real wierd.

Im using one pc with windows 7 and another with XP.
When I copy a file on the pc with Windows 7 to the shared folder, I can see and access the file fine from the XP pc.

However, when I move (Ctrl+X) a file to the shared folder on the pc with Windows 7, the file does not apear when I go to the shared folder from the XP pc.

Anyone knows what Im doing wrong?

BY THE WAY, is there a way to share the entire C drive or we are strict to the public folders? Its wierd that I gave full access permissions to the C drive, yet an error occurs while trying to access from XP. Only the public folders can be accessed.

You still need to allow premission to access the shared files on the Windows 7 machine. Just set up permissions on the Windows 7 machine by going to "Network and sharing center" and then to the left choose "Change Advance sharing settings". The select the settings in the pictures below.

You should also have access to the entire C drive once you do that.

I've been using my XP machine as my file server and it works perfectly.

I have already done all of that and I am still having the same issues.
I have gone through so many tutorials, and I have no Idea what I am doing wrong.
