* When dealing with computer file sizes, it is common to append a post fix
|
|
* such as B, KB, MB or GB to a string in order to easily denote the order of
|
|
* magnitude of the file size. This plug-in allows sorting to take these
|
|
* indicates of size into account.
|
|
*
|
|
* A counterpart type detection plug-in is also available.
|

|
|
* @name File size
|
|
* @summary Sort abbreviated file sizes correctly (8MB, 4KB, etc)
