Size on Disk refers to the total bytes used by the file blocks used to store files. Depending on what filesystem is used and how it has been set up (what the block size is) the results will be different. So ignore that figure.

How big is a file on a disk?

Each “block” on the disk could be up to 32,768 bytes. So a file of 32,769 bytes will need two blocks, using 65,536 bytes on the disk. The wasted 32,767 bytes is usually called “slack” space. Generally NTFS disks have “4k” “blocks”, or 4,096 bytes per block.
