LLNL XDIR manages files in a heterogeneous network. It provides a graphical user interface for drag-and-drop file transfer and for direct manipulation of local and remote directories. LLNL XDIR has the ability to view information in four different formats, including hierarchical and iconic views. Based on UNIX, the C programming language, OSF/Motif, and the file transfer protocol FTP, LLNL XDIR is highly portable.
