Hello seowming and welcome to SevenForums.
Have you checked if your files are hidden? Go to Control Panel > Folder Options > View > Show hidden files and folders
(The same using command prompt: type dir C:\\abc...\ /ah to see if if there are hidden files in your folder. If so, you have to use attrib command within your abc... folder to unhide files. Type cd c:\\abc... and press enter, then type attrib -h *.* )
That's about only thing I can think of now.
