[SOLVED] SSD has less available storage than I calculated

[Stef Pro]

Windows file explorer says that my SSD has 125 Gb free out of 237 Gb. So I went into the drive and checked how much storage every file uses. After I subtracted the Gb of all the files from the 227 Gb of the SSD, I calculated that the SSD should have had 150 GB available. That's 25 more than what is displaying. So, what's happening here? Are there any hidden files, or is file explorer not accurate with the calculation of storage?

A LOT of hidden files that you do not see in File Explorer.

pagefile, hibernation are the two big ones.

Also, every file system (NTFS, FAT, etc) does use disk space to describe file properties (meta data) and location on disk. You'll notice this when you do "view properties" for many files, you'll se that there is a noticeable difference between the file size and the total space on disk occupied by that file. How much difference will vary depending on file system and the block size of the file system.

As a consequence, A very large number of small files will result in higher disk usage than a small number of large files.

Nice to see the problem solved. However, I did found an informative youtube video with more steps explained than mention here:
