Problem
You have a file size (e.g., from a CFDirectory tag) and you want to output it formatted in the most logical size format.
Solution
Simply call the function, passing only the size in bytes. Designed as a cfc to share w/ all your apps, it can also be easily reformatted to run as a custom tag or inline.
