A .DAPROJ file stores authoring structure rather than media, including menus, chapter markers, and video ordering plus file paths to the real content, so moving or renaming clips breaks the project; to use it, open in DivX Author, inspect in Notepad only for path clues, and export through the program to produce a playable result.
A DAPROJ file shows missing clips when paths change because it points to the original file locations, so to get a playable result you must reopen it in DivX Author and export/build the final output; if you still have the software and the source videos, you can continue editing menus, chapters, clip order, and settings before authoring the finished project, while without DivX Author the file still helps you identify which videos and paths were used—even though missing media must be restored or re-linked for the project to work.
To open a .DAPROJ file, only DivX Author interprets it properly, so double-clicking or using Open with → DivX Author is the right workflow, and inside the software you can load or relink videos if the project reports offline media; if you no longer have DivX Author, viewing the DAPROJ in Notepad can reveal filenames and paths, but other programs can’t meaningfully open or play the project.
What you can do with a .DAPROJ file hinges on whether DivX Author is installed, since having DivX Author lets you resume the entire authoring workflow—editing structure, menus, navigation, and chapters—before exporting a proper finished output, while missing-media issues are fixed by restoring/relinking video paths; without the software, the DAPROJ mostly helps identify which videos were used, but you can’t recreate the authored build.

A common issue with a .DAPROJ file is that it opens but no actual videos load since the DAPROJ only references source videos; correcting folder names, drive letters, or filenames—or using DivX Author’s Locate/Re-link option—restores the project fully so you can then rebuild and export the finished authored video.
