Windows 10: C drive free space reduced by hidden files

Hello, everyone, I'm Arjun.My C drive is showing wrong information about the space used.All the folders in the C driver cumulatively use 62.5GB and my C drive is about 195GB.But the C drive is showing the amount of free space is only 92.6GB.Where is this space approx. 40GB gone?And how can I get back this space?

Free space in C drive keeps reducing

I have been using Win 10 Pro on my laptop for a while now. And I have noticed that the free space in my C drive keeps reducing on its own.

I tried adding the total size of all the folders (including hidden folders) in my C drive (eg Windows, Program files, Users, etc.) and it comes to around 51GB. The total size of my C drive is 96.8 GB and on "This PC" it shows free space of just 15.4 GB.
A few days back it was 19.4 GB.

Whats wrong with my C drive? Whats eating up all the free space?

 

Unallocated Space to C Drive

Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.
