<p>Note: This is an estimate only, using a 'block' size of 4096 bytes ... in most 
operating systems, the hard disk space is divided up into blocks, sometimes called 
'sectors' ... that means, even a file of just a few bytes in length, takes a minimum of one 
sector, or block ... while its file size will remain only a few bytes, it will occupy one, 
or more, complete sector, block, on the disk ... and then there are the directory enries 
themselves ... in this estimate, assumed to take one block ...</p>

<p>Also each file occupies some bytes for the file name, as a directory 
entry ... and space for the names of the directories, the folders, on the disk ... but these 
extra bytes for the directory entries are not usually counted ...</p>
