Unsafe Mimetypes allows users to define extra media types not allowed by the standard WordPress installation. Users will often encounter the message ‘Sorry, this file type is not permitted for security reasons.’
This plugin allows the site admin to upload and distribute files other than the basic set WordPress allows by default. This plugin allows the user to define a list of extensions they wish to allow. Administrators can choose to allow only Administrators or all Media Uploaders to be able to add the defined types to the library.
Note: This plugin does not permit the user to change the maximum upload size, which may be needed for large multimedia files.

Unsafe Mimetypes

Unsafe Mimetypes allows a WordPress admin to decide which file formats can be uploaded to the media library

Manage Upload Types enables an administrator to see and change the list of file types that are permitted as file uploads to the media library. This is accomplished by adding an ajax-driven table to a panel on the Media Settings page. Each row has a delete link. Confirmation is required for deletions. There is also a small form to allow additional rows to be added. The form is aligned with the table and contains two text entry boxes. The first is for a file extension or list of file extensions separated by pipe symbols (‘|’) and the second is for a MIME type to be associated with files that match one of those extensions.

Manage Upload Types

This plugin adds a panel to the Settings->Media page, enabling changes to the file types which are permitted to be uploaded to the media library.
