Strange seemingly-unused space on my SSD

Question

This is what I have in Disk Management:

I'm wondering what those partitions are on Disk 0, and if there's ways I can use them to increase the size of C: Seems like a waste.

Answer 1

Your SSD has about 200 GB in the main NTFS partition, which should be ample for the Windows OS files and some data. Changing the partition scheme is not suggested, since a mistake can make your PC completely unusable without full reinstallation of Windows, losing all your files. There are things to do to make more room:

• Perform Disk Cleanup, both from Windows and with a third-party tool, such as Wise Disk Cleaner.
• More space can be freed by removing old update files and backups, at the expense of being unable to revert to the state before updates, using DISM and SFC.
• If you have another drive, move some or all of the default user folders, such as Music, Pictures and Videos, to that drive. This can be an external drive, though avoid flash USB drives, which can be slow to save data.

If you do decide to remove a partition and juggle the others around, make a full disk image first, so you have a way to back out of an unfortunate mistake. Caveat probatorem.
