Here's a tip - if you need to move or back up a large Jade database file (over 4gb), you may have noticed WinZip doesn't handle it. Well, the Jade Database Utility (jdbutil.exe) does handle it. It is not as fast as WinZip, and the compression is not quite as good (although I didn't try all the options in the ini file), but at least you can do the big files. You get one compressed file per input file.
Thanks to abduhl (or was it nik?) for the tip.
You can also use the Binary::compress and uncompress methods to write your own. That way, you could also split up the compressed file to spread it across multiple CDs, or combine multiple input files into one compressed file. I have sample methods (without the splitup) if anyone is interested.
Cheers,
