AD file extension - AppleDouble encoded file

What is ad file? How to open ad files?

File type specification:

Encoded and encrypted file type icon Encoded and encrypted file type

ad file icon: ad filetype icon

The AD file extension is related to the AppleDouble and used for its encoded files.

AppleDouble leaves the data fork in its original format, allowing it to be edited by normal Unix utilities. The resource fork and Finder information, both propietary and lacking editors under Unix, were combined into a second file.

The AppleDouble format should be the primary format when sending a Macintosh document. It makes it possible for a user that can't decode the AppleDouble header to read and use the Data fork of the document. It also keep the Macintosh specific information in the AppleDouble header, so a user who can decode the AppleDouble header can get the extra information, such as customised icons, which is not essential to the document itself.

Mime: application/applefile

Help how to open AD files:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert file with extension AD:

As far as we know, this .ad file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
