What is a DCF file?
A DCF file is a media file that has been copy-protected by Sony Ericsson DRM Packager or another Symbian OS DRM app. It contains media, such as a ringtone, song, or video, that can be played only on an authorized smartphone. DCF files are similar to .DM (DRM Delivery Message) files, except their rights object is stored in a separate file.
More Information
On smartphones that use Symbian OS, such as some older Sony Ericsson and Nokia smartphones, users could purchase media from various online stores (e.g., the Ovi Store). Some of this media was saved in the DCF format.
To create DCF files, content creators used DRM applications such as Sony Ericsson DRM Packager. Content creators could then upload their copy-protected media files to the appropriate online store, for purchase by users.
How to open a DCF file
The media a DCF file contains can be played only on an authorized smartphone. As such, you cannot open a DCF file, or play the media it contains, on a non-authorized device.

A DCF file may also be a component file used by Dyalog, an APL-based development environment and programming language. It contains an APL array. DCF files are used in Dyalog applications and referenced by Dyalog File Server.
More Information
APL (which stands for A Programming Language) is a programming language that developer Kenneth Iverson developed in the 1960s. It is a symbol-based language that allows developers to concisely implement functions that create and manipulate multidimensional arrays.
While APL itself was last updated in February 2001, some developers, especially those working in the financial, insurance, and data science industries, still develop APL-based applications. Dyalog is an implementation of APL that allows developers to create, edit, and manage corporate APL-based applications.
Dyalog applications and the Dyalog File Server frequently reference Dyalog component files, or DCF files. These files are plain text files that contain a Dyalog array. Dyalog applications and Dyalog File Server use DCF files to load array data when a user performs a function that relies on that array.
How to open a DCF file
You can open a DCF file in Dyalog (cross-platform). If you do not have access to Dyalog, you can open a DCF file in any text editor to view the array it contains.
