This action is rather powerful, and lets you use information stored within your files when renaming them. Not only can you utilise
the standard file information, such as the created or modified dates, but you can also use MP3, JPEG and RAW file information.
This lets you easily use the name of the album's artist or the shutter speed of a photo in the new name of the file. Apart from
the standard 'Rename Area' and 'Beginning at' options, there are a couple of other options.
The first is the 'From the directory' drop down box, which shows you every available directory (i.e. category) of information
in the file. The second is only filled when you select a directory, and this is a list of all of the names of the information
within that directory.
When you select a name, the files in the Preview screen will be renamed using the value for that name that exists in each file.
A file will only have information inserted into it's name or extension if that information comes from inside itself - another
file's data will never be used. And if a file doesn't have that directory, name or value inside itself, nothing will be inserted
into it's name or extension.
Important note: None of the information inside the file will ever be deleted or altered in any way.
