Hi,

Why is there a discrepancy in used space on my laptop's NVme SSD, in file explorer vs. Tres size as displayed in the attachments?

Is that normal?

Shouldn't they be both equal?

Hoping to hear from the experts.

Thanks.

I believe 45GB is just 44.3GB rounded, from which the Windows folder is about 20GB, the Program Files and the Program Files (x86) folders (maybe the hidden ProgramData folder as well) are about 10.4GB and the rest GB is user data.

Hi Alexey,

Also size is the actual size of the file in bytes.
Size on disk is the actual amount of space being taken up on the disk.

If you really want to get details, use this:
