8:54 AM EDT 		One neat trick with the original Norton Utilities,

Use directory-sort to put the files in the order I wanted.

Then run defrag, which would write the files to the drive in the same order they were in the directory listing.

Maximum optimization of disk read functions!

I am so very, very glad those days are over. Not that I don't respect hand optimization, I consider it a sign of a true artiste. Linus talking recently about the lovingly hand-optimized low-level look-up that Linux does faster than any other OS comes immediately to mind.

I'm just very glad that I can ignore all that and just play. What? Disk getting full? Where's that 2TB backup drive!
