What to Do When a .DVO File Fails to Open

Because .DVO files originate from different programs, they aren't universally openable.

Identify the Source: A legacy DOS workflow suggests a DESQview overlay file, while a colleague's export may be proprietary data.
Check the Header: Inspect the first bytes in a text or hex editor:
- "MZ" indicates a DOS executable or driver.
- Readable XML/JSON suggests a configuration file.
- "PK" means it's a standard ZIP archive.
Use the Original Software: The original program is usually required; try DOSBox, Symantec Corporation's DESQview, or ask the sender if uncertain.
