The File entity module extends the capabilities of the core File module.
File Entity defines 5 File Types - Application, Audio, Image, Text, Video. The Media module adds an additional File Type - Other (currently these File Types are hard coded and cannot be changed).
When files are uploaded they are automatically assigned the appropriate File Type based on the file suffix.
The File Types as currently defined are:
- Images - .png, .gif, .jpg, .jpeg, .ico
- Videos - .mov, .mpg, .flv, .m4v, .mp4, ,ogg, .ovg, .wmv
- Sound files - .mp3
- Text - .txt
- Document files - .doc, .xls, .pdf, .ppt, .pps, .odt, .ods, .odp
- Other - ??
Each File Type can have fields. This allows for additional information to be stored along with a media file such as Title, Description, Taxonomy References, Node References, Location, Date created, License information etc.
File Entity now allows developers to create their own File Types. Then you can have an image file type that stores pictures of employees and has fields about that employee. You can have another image File Type that stores images of products and the fields are product information.
