Windows 10: How to resize C: partition

I have the issue that my C: drive is pretty much out of space, I keep getting low space warnings and I've tried moving everything I can to my D: drive. Basically it's a 1.5TB disk with C: and D: partitions. I'd like to take some of the space from D: maybe 100GB and move it to C:. It seems very hard to find a tutorial to do just that.

I feel like I can do it in Disk Management simply by shrinking D: by 100GB (or whatever) and then extending C: by that same amount but I want to be sure that I can do that without losing any data. I need this computer for work (and for play). Is there a straight forward tutorial on doing this somewhere? Thanks.

I would increase the size of the System Reserved Partition before C partition on Disk 1 from 100 mb to 500 mb taking the disk space required from the C partition.

I suggest you use Easeus Partition Master (freeware) to resize your partitions.

You first need to reduce the size of C. This enables you to increase the size of the System Reserved Partition by taking up the space C has vacated. When you resize partitions it is all about before and after. Thus in the simple operation of C giving
up space to the System Reserved partition when resizing or reducing the size of C the free space needs to be created before C. This enables you to resize the System Reserved partition by expanding into the free space you now have before C. When you have done
the above apply the changes.

How large is the system reservation partition and how much free disk space within the partition? You could make this small partition a bit larger using
Easeus Partition Master (freeware) to resize your partitions.

To increase the size of the system reservation partition
you first need to reduce the size of partition after the system reservation partition. This enables you to increase the size of
the system reservation partition by taking up the space the next partition has vacated. When you resize partitions it is all about before and after. Thus in the simple operation of D giving up space to C when resizing or reducing
the size of D the free space needs to be created before D. This enables you to resize C by expanding into the free space you now have after C. When you have done the above apply the changes.

There is a flow in your plan. It's that pesky 350MB recovery partition because you cant extend or merge to D: with it in the way. It could be done only with adjacent partitions.
I don't know haw you ended up with so many recovery partitions. Normally only one is needed.

 

Huh... This is just the way it came. It's an Asus computer.

 

Was it new ? This looks like 2 upgrades were done.

 

Well I bought it new but I think it came with Win8 So I probably upgraded to 8.1 and then to 10.

 

That would do it. Personally, I don't use any recovery partitions, that problem is in my case solved by regular Macrium Reflect backup. If you don't need them you can get rid of middle and last one, not sure what could be done with first one. Last one is taking a lot of space.

 

Huh Well I don't think I have any other means to recover if I need to. Would it be possible to get rid of them now, resize, then create a new one later?

 

Trick would be to find out which one is for which. The one for last upgrade is probably only one needed. One is probably factory one and would bring you back to initial windows installed on it. I have no idea how to find that out.

 

I was just looking at this Macrium Reflect, it says the free version can reorder and resize partitions.

 

You can do it without it, right from disk management but that's not the problem. Problem is finding out which one you need to keep.
With MR you can just make backup of needed partitions and than recover just them without others but that doesn't make right choice of what to keep and what to discard.

A lot of discussion is made about recovery partitions but on Windows 10, they are not as important as on earlier versions.

On Windows 10, they are only used if you use the "reset my pc" option. Since you can do effectively the same from a windows 10 installation drive, you can delete them without any significant impact (other than a bit of time to download windows 10 installer on to a usb stick).

You can also create a barebones usb recovery stick using

control panel, recovery, create recovery drive and select to copy system files.

On my 32gb tablet, I delete all recovery partitions and create a Macrium Reflect image backup instead to another drive as they take up valuable space.
