Incorrect storage space display?

My Windows laptop settings state that apps and features take up 41.7 GB. But if you add up the storage space of all apps and features, you don't come close to 41.7 GB. I previously downloaded a large mega file, but deleted it again, if it could have something to do with it. Can anyone explain to me how this comes about and how to fix it?

Could be loads of pictures or documents try to berigen your hard drive

The apps and features listed are by far not everything that is on a PC and is included in the total.

Therefore, the sum can't be exactly the same as the value.
