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 offline footage when folders change since it stores absolute references, and you need DivX Author to reopen it and produce a watchable result; with the software and original videos, you can resume editing menu layouts, chapters, navigation, and clip sequencing before exporting the final build, while without DivX Author you may still inspect the file for video names/paths to locate missing assets, though you must restore or re-link sources manually.
To open a .DAPROJ file, DivX Author is designed to interpret it, so open it via double-click, Open with, or File → Open inside the app; missing/offline media notices appear if videos were moved, requiring relinking or restoring folders, and if DivX Author isn’t available, examining the file in Notepad for path references is the only practical alternative, as other software can’t open it in a useful way.
What you can do with a .DAPROJ file varies with your ability to run DivX Author, allowing full project editing and export when the software is present, including fixing path-related missing-media issues, but without it the DAPROJ mainly acts as a list of filenames/locations to help recover source videos, not as a file you can convert into a completed authored movie.
A common issue with a .DAPROJ file is offline media in the timeline caused by moved, renamed, or un-copied source videos, since the project points to fixed paths; restoring those paths or selecting new ones through DivX Author’s re-link tool typically restores all menus and navigation settings and allows you to export the final authored result.
