possible to get the fully qualified path name for file updloads?

Hi, I'm doing file uploads through PHP and now have a need to retrieve and store the original fully qualified directory path name used for the upload. For example if the user copied image file sample.jpg from c:\temp I need to retrieve and store the c:\temp\ in addition to the sample.jpg that I am already storing. The directory path does not seem to be availble anywhere. Is there some way to get this? TIA! Andre
