Larry --

I like the idea of having one filename extension associated with 
PSN4-format files.  The present method of using a different three-character 
extension for each sensor makes handling these extensions using the usual 
Windows file type associations almost impossible.

From SDR's point of view, if people are running SDR from a Windows 95 or 98 
machine booted to dos, doesn't that arrangement support long file names?

I believe naming files according to a system used by other organizations is 
desireable.  I think there may come a time when data is shared between 
networks much more than it is now.
