Member variable HttpUploadedFile():NameOnDisk Foundation
Contains the full pathname of the file on the web server’s hard drive.
:NameOnDisk contains the fully-qualified path and the name of the file. Note that the physical name of a disk-based file is guaranteed to be unique in the folder where the file is uploaded to. Thus :NameOnDisk differs from the logical name accessible via the member variable :Name.
For memory-based files, :NameOnDisk contains the empty string. :IsOnDisk can be used to determine whether the file is stored on disk or in memory.
