Plugin for storing any type of file.

Default template displays download link with icon (if available) and file size.
|
|
|
|
This could be updated to use the mimetypes library to determine the type of file rather than
|
|
storing a separate icon for each different extension.
|
|
|
|
The icon search is currently performed within get_icon_url; this is probably a performance concern.
