Size and size on disk

Hi, guys. I was just wondering, I know that when you right click on a file and select properties, the size on disk should usually be at least slightly bigger than the size. But what if, rather than being any bigger, it matches exactly, down to the very last digit? Could that mean that there's something wrong with the file, that it's incomplete maybe? Or does that just happen sometimes? Sometimes the size on disk is bigger and sometimes it isn't? Thanks.

 

The size on disk size of a file will be cluster aligned (typically 4KB / 4096 bytes) unless all the file attributes and content of the file can be contained within one Master File Table record.
So in cases where the file size is an exact multiple of the cluster size, both its size and on disk size will be equal.

 

Great, thanks.
