I take it that you have a binary file that takes a file name and proceses the file contents. Sometimes Unix binaries are written so that a file name of '-', (just a dash), causes it to take input from stdin so that the piping mentioned in a previous reply could work. On some of our unix systems /tmp is set up as a 'virtual disk' It quacks like a normal disk filesystem but is actually implimented in RAM/virtual memory, and is faster than normal disk access. (Unfortunately we are not allowed to save multi-gigabyte files there as it affects other aspects of the OS).
Maybe you can mount a similar filesystem if you have the RAM. -- Pad. -- http://mail.python.org/mailman/listinfo/python-list
