Networking XP With Windows 7 Machine

I am trying to link a Windows 7 machine with a laptop running Windows XP. The workgroup on both computers is the same. On the Win7 machine, I have a couple of folders set to be shared. The first is the C Drive and the share name is C-drive. The second is Quickbooks that I have named Quickbooks. On the XP machine, I went to map network drive and in the blank typed \Remote1C-drive. It asked for username and password and just like that we were connected. But I can't see all of the files on this drive. I don't even see all of the folders - one of which is Quickbooks. So I tried \Remote1Quickbooks and Windows XP couldn't find that path even though I'm positive that folder is shared on Win7. So no matter what I try, I can't see this folder on the XP machine, I even tried copying this folder to other locations around the computer and setting up shares in hope that something would work, but it never did. So I went back to the C Drive share on the XP machine. I tried to go in reverse, creating a file and putting it on the root of the c drive (I did this on the XP machine, but the file should have actually been located on the Win7 machine. When I check Win7, the file didn't exist. So I tried the other way. I right clicked on the c drive in Win7 and created a new bitmap image file. Back to the XP laptop, that file doesn't show. But if I look at the c-drive on Win7 from the xp machine, I see several other folders and some of them like Program Files contains actual files. But some of them are just empty such as \Remote1C.
