I have been deliberately keeping out of this stuff, but I would like to point out that there was a thread back in late 2002 in which all this stuff came up. Back when use of XML was being debated, I suggested that we could use gzip for compression and then it wouldn't matter if the tags were long or short as the file size would be about the same. The use of .lyx.gz or .lyz was debated although I forget the outcome. I think .lyx.gz makes perfect sense to anybody who looks at it. They can take a stack of .lyx files they haven't needed for a while and gzip them legitimately. They can for whatever reason do the reverse. Just as long as the correct datestamp is written into the .gz so gunzip will keep the right stamp on the unpacked file (or is it better to omit this?). The filename shouldn't be written or if it was renamed, gunzip might change it back. I think in the case of unpacking, the user should be warned if an overwrite is taking place, just as for File->Save As or File->Save if it was externally modified. Have fun, Darren
