Fragmentation
Um, if you're going to be doing a full backup of your hard drive _anyway_
(and prior to running any de-fragmenter, however highly recommended, it is
a good idea), you might strongly consider partitioning the 80 megger into
two or seven pieces. Then leave one partition empty or full of
don't-really-require files. The reason? If you have a glitch on one of
the other partitions, you can use Dave Haynie's DiskSalv to recover from
the harmed partition into the spare partition (they have to be the same
size).
