File Sizes

When checking file sizes there are two sizes "size" and "size on disk" please can someone explain what the difference is between these two. Thanks!

You will have to be a bit more specific that that?


Where are you checking these sizes?

A disk is divided in blocks (called Sectors i think)

Lets just says a Sector is 4 kb and your file is 6 kb. The file size is 6 kb but the space on disk will be 8 kb. This is because you can only have one file occupying a sector and if a file uses even one kb of a sector the next file must start in a new sector.

So theoretically the file is occupying 2 sectors (not one and a bit) and is said to occupy 8 kb on this disk instead of the 6 kb true size of the file.
