Increasing C Drive

[KatheD]

I am looking for a product to increase my C drive - taking away from my D drive.  I have found many but not sure what wont harm my computer.  I trust CCleaner - been using it since the start.  So figured I would ask here for advice

thanks

i would do that only with a new set up of the whole system - new os-install

 

because of the contiguous partition sections of the hard drive and the associated access times

You can do it manually using the disk management tools built into Windows.

But it's a bit of work and entails deleting D (or another partition) to create some free space, then expanding C into part of that free space, then re-creating a smaller D.
Here's a guide to doing it (from a company that has it's own repartitioning tool):

I've never used one of the advertised tools, the few times I've wanted to repartition a drive I've used the built in Windows tools.
I have seen decent reviews about the one in the above link but have never used it, there is a free or a paid for version - your best bet is to read the reviews of a few of them yourself, particularly on technical sites and computer magazine websites.

Whatever you do then if you are going to attempt this you should make a clone/mirror image of your drive before starting. (using Macrium Reflect or similar).
That way if it goes wrong then you have the clone/mirror as a backup.

Why not just move some of your data folders to the D drive? That would be the same as 'taking away' space from the D drive, and exceedingly easy.
