What is a .DRC file?
The file extension .DRC refers to a DRM Rights Object file. This type of file is used in the context of Digital Rights Management (DRM), which is a technology used to control how digital content, like music or videos, is used and distributed. The .DRC file contains important copy-protection information that helps in managing the rights associated with digital media.
The information inside a .DRC file is stored in a format known as WBXML, or WAP Binary XML. WBXML stands for Wireless Application Protocol Binary XML, which is a compact form of XML used mainly for mobile devices. This format helps in reducing the size of the file, making it easier to handle on mobile platforms.
A key component of the .DRC file is that it includes the encryption key needed to unlock the content of a .DCF file. A .DCF file typically contains the actual media content, such as a song or video, that is protected by DRM. The .DRC file works alongside the .DCF file by providing the necessary key to decrypt and access the content in the .DCF file.
To open and use .DRC files, you can use several different programs. Although the Sony Ericsson DRM Packager, which was specifically designed to handle such files, has been discontinued, you can still open .DRC files with any basic text editor. However, viewing the file in a text editor will only show you the encoded content, not the actual usable data or media. To properly use the DRM-protected content as intended, specific DRM software or devices that support the DRM format used by the .DRC file are required.
