A DGW file isn’t a fixed standard format, and what it contains varies based on the program that produced it, often serving as a proprietary working file that keeps your CAD or design data such as geometry, layers, and view settings, though sometimes it acts like a full drawing while other times it relies on linked resources that may go missing on different computers, and occasionally it’s even a misnamed ZIP or PDF, so the simplest way to understand what you’re dealing with is to identify the source software or check the header signature to figure out how it should be opened or converted.
A DGW file works as a native design or project file for the software that created it—just as PSD aligns with Photoshop or DOCX with Word—because it encodes information according to that program’s structure and feature set, preserving editable elements, layer systems, measurement settings, templates, view presets, and linked items that generic formats would discard, which explains why your OS can’t open it without the right software, and why some DGW files load complete drawings while others depend on separate assets, making the surest way to open or convert it to identify the originating application or inspect the file signature.
A DGW file often trips up users because an extension is basically a label rather than a fixed format, meaning different software developers can assign .dgw to completely different file types, and since your operating system relies on simple extension associations rather than file inspection, the wrong program might try to open it or flag it as unknown, making it important to identify the original creating software to know how to open, export, or convert it properly.
DGW files can be interpreted through several “buckets,” reflecting how different software uses .dgw, with one bucket being full CAD-style drawing files holding geometry, layers, and view configurations, a second bucket being project/workspace files that rely on external linked materials, a third bucket being packed export sets meant for import within the same app, and a final bucket being mislabeled files that are really other formats like ZIP or PDF, identifiable by checking headers or testing them as archives.

A project/work DGW file acts as a “save state” for an entire project rather than a self-contained drawing, because it keeps instructions and references for rebuilding the workspace—what drawings to include, where linked images sit, which fonts and libraries to load, and how units and views are configured—so it relies on external paths like C:\Projects\Job123\assets that may break when moved, often appearing with related folders such as textures, libs, or references that must accompany it.
