DAZIP
From Dragon Age Toolset Wiki
DAZIP files are packages of exported resources ready to be installed and loaded into the Dragon Age game. The format is actually just a renamed ZIP file, and can be opened by any zip editor to manually extract or manipulate the contents.
Inside are the exported binary resources for a module, packaged into ERFs and arranged in a directory tree corresponding to where they will be placed when installed. Also included is a manifest XML file that contains information about the module, such as title, release date, version number, and so forth.
