Active Media Eclipse uses .erf files as resource files needed by the software. They are intended to be used by Eclipse rather than as general-purpose documents.
The file is associated with Eclipse on Microsoft Windows, Apple macOS and Linux/Unix. Its contents and purpose are normally interpreted by Eclipse itself.
Open an .erf file with Eclipse from Active Media on Microsoft Windows, Apple macOS or Linux/Unix. In most cases, the file should be opened from the Eclipse project or installation that uses it rather than treated as a standalone file.
If Eclipse does not recognise the file, it may belong to a different application or its associated project files may be missing.
An .erf file is not normally converted as a standalone file. It is a resource used by Active Media Eclipse, and project-specific export options may be available from the software.
Keep the file with its Eclipse project or installation when moving or archiving it.

The erf file extension is mainly related to Bioware Aurora game engine and used for its default archive format.
The Encapsulated Resource File (ERF) format is one of BioWare's methods of packing multiple files into a single file so that they may be treated as a single unit. In this regard, it is similar to .zip, .tar, or .rar. BioWare Aurora Toolset files that use the ERF format include the following: .erf, .hak, .mod, and .nwm. The example ERF Editor is an internal BioWare tool (Windows only).
Use compatible tools to work with *.erf files.
Probably cannot be converted to other formats.

SGML Visual DTD uses this file to support entity references in SGML document type definitions and related documents. Entity references allow commonly used text or other replacement content to be defined once and referenced where needed.
SGML was designed for sharing machine-readable documents in large government, legal and industrial projects that needed to remain readable for several decades. It was also used extensively in printing and publishing. One of its first major applications was the second edition of the Oxford English Dictionary, which was and is wholly marked up using SGML-like markup. Its complexity limited its use for small-scale general-purpose applications.
Open the file with SGML Visual DTD when it is needed as part of an SGML project. Because an ERF file is text-based, a plain-text editor can also be used to inspect it, but changing its entity definitions may affect documents or DTDs that reference them.
An ERF file is a supporting SGML resource rather than a standalone document, so it normally has no useful conversion target. Preserve it with the related DTD and SGML documents, or edit its entity declarations as SGML text when adapting the project to another compatible SGML tool.
