Is there a simple way to move memory from my D drive to my C drive (Sony Vaio
S VGN-S3XP). PS I'm non technical so lay-mans language please.
First, the word "memory" refers to RAM, the thing you probably have
256MB or 512MB of. Your C: drive and D: drive don't contain "memory";
they contain disk storage space.
I assume from your question that you have a single physical drive,
which has been divided into two partition, C: and D:. Is that correct?
You can not literally move disk space from partition to another, but
you can change the partition structure of the drive to make one
partition bigger at the expense of the other. I assume that's what you
want to do.
However no version of Windows before Vista provides any way of
changing the existing partition structure of the drive
nondestructively. The only way to do what you want is with third-party
software. Partition Magic is the best-known such program, but there
are freeware/shareware alternatives. One such program is BootIt Next
Generation. It's shareware, but comes with a free 30-day trial, so you
should be able to do what you want within that 30 days. I haven't used
it myself (because I've never needed to use *any* such program), but
it comes highly recommended by several other MVPs here.
Whatever software you use, make sure you have a good backup before
beginning. Although there's no reason to expect a problem, things
*can* go wrong.
