Many install programs on C: and save data to D:.. in the event that the OS
has to be re-installed, all important stuff is separated away..
One can install programs to D: too, in the event that C: starts to fill up..
A separate partition is easier to back up.. one can just select everything
within the partition for saving to media of choice..
Of course, a hard drive failure will take everything with it, something that
happens all too often these days.. sensible folk have two physical hard
drives installed..
I have two physical drives that contain a total of six partitions.. C: is
the main OS, and D: is a temporary scratch disk.. E: runs Beta OS'es, and F:
has my games installed.. G: is the CDRW, H: is where I keep installation
media like device drivers drivers and all of the silly freebie programs that
I use.. and I: is my main backup/archive drive..
There is also another computer on my network that has two drives, a
partition within one of them being used as a mirror for the I: drive..
Stuff organised in this way is very easy to find.. maybe you should give it
a chance.. the alternative for you is to use a program like Partition Magic
to combine the two parts.. using programs that alter the drive in such major
ways are not without problems in use.. you would have to do a backup of all
of your important stuff, which if on D: would be painlessly easy to find,
and there would be less chance of 'missing' something..
