A .DAPROJ file is a structural script for DivX/DVD-like projects, holding menu designs, navigation, clip order, and pointers to external AVI/MP4/DIVX media rather than embedding video, which is why broken paths cause missing-media warnings; load it in DivX Author, review text paths if needed, and generate the final video using the software’s export tools.
A DAPROJ file loses track of media when folders change because it only stores references, not the videos themselves, so you must load it in DivX Author to rebuild/export the final playable result; having the software and original clips lets you resume editing menus, chapters, and ordering, while without DivX Author you can still open the project in a text editor to find filenames and paths, but any missing footage must be recovered or re-linked.
To open a .DAPROJ file, you’ll need DivX Author to use it properly, accessible via double-click or File → Open, with relinking required if videos moved; if you no longer have DivX Author, viewing the file in a text editor may expose the referenced paths, but otherwise no other tool can meaningfully open or rebuild the project.

What you can do with a .DAPROJ file relies on having DivX Author plus the original videos, because with the software you can reopen the project, fix missing-media links, reorder clips, refine chapters, redesign menus, keep the same output settings, and then export a real watchable result—while without DivX Author the file mainly serves as a reference map that lists filenames and paths so you can recover the clips, though you can’t rebuild the authored menus or finished package.
A common issue with a .DAPROJ file is that clips seem to vanish because the project only knows the original file paths, which break if you relocate or rename videos; re-creating the old directory structure or using the Locate/Re-link prompt lets DivX Author reconnect to the clips, bringing back menus and chapters so the final export can proceed.
