I installed Mac OS X Leopard on my laptop a couple of weeks ago, and tried out the spiffy new Time Machine feature which does differential backups to a hard drive. On the first run, of course, it had to back up the whole machine and I was a bit startled to see that it was copying over a million files. Of course, lots of those are system and applications files, but my documents folder, which is mostly stuff I’ve created myself, has over 250 000 files. And today I got a message from Eudora telling me (not for the first time) that my Inbox could only hold 32000 messages.
I can remember when I knew, by name, every file on the computer, and what it did. It was not that hard with a machine (128k Mac) that ran off a couple of 400k floppy disks.
