Funny, I was just reminiscing about that oldie just the other day. DiskDoubler dates from the days when hard drives were phenomenally expensive and comparatively slow. At that point, it made sense to compress/decompress on the fly, so a few utilities came out that more or less transparently kept files on the HD compressed. If you don't have the AutoDoubler component, don't worry about those compression methods. Basically, AutoDoubler (as the name implies) was the component that did it's thing on the fly. What's more, it would run around during idle time and find things that weren't compressed and would compress them. The two different methods were a less-compressed-but-faster and a more-compressed-but-longer-to-compress. AD would do the first in real time and then as it found time, would do the other. The DiskDoubler app was a standalone app to do file compression -- you use it just as you would the StuffIt application. I believe StuffIt still will decompress DD & AD compressed files, but I'm not sure. Nowadays, it probably makes sense to just use StuffIt, but I suppose if you're using an old enough PowerBook with an appropriate version of the OS and you're bumping against the limit of your HD, then using the AD component might still make sense. On any PB that supports IDE drives, though, you're much better off just getting a bigger HD. Thinking about it, there are only two reasons I use file compression anymore. The first is to consolidate folders populated with many (100's to 1000's) old files so that the file system isn't having to keep track of all those files. The other is when I need to transfer a file, either to a Zip (if it doesn't *quite* fit) or via Internet. So, my advice is to consider carefully just what your need really is for this. - Eric. -- Eric Strobel ([EMAIL PROTECTED]) ===================================================================== *I'd* rather wear fur than go naked! ===================================================================== -- PowerBooks is sponsored by <http://lowendmac.com/> and...
