Delft, november 25, 2004 Footer9 Problem The sometimes complex structured files are difficult to process as it is often unclear what files are exactly required and which files are extra. Also archiving in the long term is almost impossible. Formats may not longer be supported Media will decay Autorun options will not start from within a database or even after downloading At the moment we ZIP complex reports (well seismic)
