In the screenshot I see that these files are allocated for twice the size (estimated) as the actual file.
If this is true:
"A file that is 4098 bytes is 2 bytes larger than a file allocation unit so it will require two file allocation units which means that it will take up 8196 Bytes (8 KB)"
Then I don't understand this.
Below is hard drive info.
