MacOS file metadata holds many useful and diverse file facts. This is not limited to file size, extension or creation date. Depending on the type and the application that created it, there is a whole lot of information available on a file’s properties.
Sender name, duration, f-stop number – and more
For e-mail messages, this can be sender name, e-mail subject and attachment type. Or duration, bit rate and musical genre for audio files. In photos, you can even find information on camera model, f-stop number and exposure time.
This metadata is useful when organizing files by specific criteria or searching for files with certain properties. E.g. images with a resolution higher than 72 dpi, audios shorter than thirty seconds, or e-mail messages containing PDF attachments.
