Extend my C drive space in Windows 8

Same with me ... C: drive partition cannot be extended. The 'extend' option is always greyed out for C:

The 'extend' option is always grey-ed out for my C:

Kindly help

This is because drive can only be extended to the left.. the resulting drive must be contiguous on your disk. You cannot extend by leapfrogging over a space that is already taken with another partition!

There is a (somewhat tedious) workaround which involves no additional software, in which I am assuming:

a) Your C drive is the Operating (booting) drive, and is in the leftmost position.

b) You have only files in the other partitions, ie not whole operating systems.

c) You have significant free space on your drive to play with and no rediculously sized files that fill entire drives.

What you need to do essentially is move the unallocated space over to the right hand side of the drive you want to extend. The extend option will then be available.

To do this, you need to shrink the partition that is currently there down to the size you wish to extend by, and then MOVE THE DATA IN IT ESLEWHERE! This is the tedious part.

You can then delete the empty partition and extend the C drive into the unallocated space.

Similar shrink, copy, paste, extend operations can be carried out to get the remaining drives where you want them. Labourious, yes, but worth it to get your structure the way you want. Reminds me a bit of the old Tower of Hanoi game you used to see on mobile phones in the old days...

Word of caution: you may need to move the recovery partition and I am not sure whether the result will still work. Windows 8 is pretty good at working out these issues though, and you can always wipe and re-make the recovery.

Oh, and one last point: Measure twice, cut once!

Hi

I also have the same issue, but the above does not work, my configuration is 47gb Health, 10gb Recovery, 155GB C drive, 133GM unallocated. I want to merge the unallocated with the C drive.

Can you help?

You will need to:

1. Free up space to the immediate right of the C drive, in what I am presuming is your D drive.

You can either:

a) move all the data from D to another partition or disk, or

b) if there is more tha 50% free in D you can shrink it, create a new partition in the newly created space, and move the data from D to the new partition. (thereby moving all the data rightwards)

2. Delete the now empty D drive.
3. Extend the C drive as far as you wish into the newly created space.
4. Tidy up by following similar steps to create space and amalgamate into the drive structure you want.

One thing I have been told is that sometimes the Disk Management has difficulty with extending into space of a different partition type eg primary, secondary or logical. In this circumstance a quick look at some freeware disk management software would be wise, eg Minitool Partition Wizard Home or EaseUSPartition Master Home.

Don't pay for them! The freeware versions are all just as good for basic use.
