How to increase disc space on C drive

C and D are separate disks.
- Your diagram shows that C is already taking up all of its disk apart from those small system-related partitions so there is no real room for expanding it.
- What you have is a computer with two disks in it, as have I. Your system specs page already says this [128GB SSD, 1TB HDD]. It is a fairly common arrangement these days and can be very useful if you set things up to suit them.

What are you trying to achieve?
- If you are trying to create more working space for your own files, you can do so by setting your "user folders" to use the D drive so C:\ only contains your OS. This can also help with backup routines because you could make system images for C:\ and straightforward file copies for your own files on D:\.
- I'd hazard the guess that you are currently using both C & D to store your own files.
- I think E:\ & F:\ are external drives, possibly connected by USB. If they are not then please say what they are.

I'd expect to suggest looking at one or more of these tutorials but I want to check I have understood the situation properly first.

Actually it can be done. These are dynamic disks, so C could be extended on the first drive. I'm not very familiar with dynamic disks, so lets wait for someone that is...

Hello @Solidjeuh,

If you like, here's a list of items you can check to help free up hard drive space.

Your Disk management diagram & the system specs you entered in this forum both show that you have two physical disks.

Your "SSD" might be anything - such as an M.2 drive, which is often a card about 2cm wide and 5cm long. There are illustrations of one particular M.2 drive in these webpages

For extending system partition (C: in your case) on dynamic disks, you have to use third party programs, like Minitool Partition Wizard.

You'll have to shrink D: partition first, and then you can extend C:
Again, I'm no expert on Dynamic disks, I would go the way Brink and Try3 described.. moving User's folders on D: drive

Here are some tutorials:

You have one HDD with two Dynamic disks defined. The first link AndreTen gave you tells you how to increase the size of the C: partition using a third party program like Minitool Partition Wizard.

It also explains why you can't do this from Disk Management, because there is no free space to the right of the C: Dynamic disk. MPW can do this for you. Or you can move personal folders, but that is not the only option.

Before you do anything you need to backup your current install. The best way to do this is to use Macrium Reflect Free to make an image backup to an external hard drive. If you don't have an external hard drive now is a good time to get one as regular backup should be a part of your normal process. You can get a 1TB external hard drive for $60 (less if on sale).
