1st Method: Open it in another program.

When you double-click SDO files, your computer attempts to open it in a program associated with SDO files. If there’s no program associated with SDO files on your computer, the file won’t open. To open the file, download one of the most popular programs associated with SDO files such as Sealed Word Document or DB/TextWorks Database Deferred Update Directory.

2nd Method: Take a hint from the file type.

The SDO file extension usually indicates it's under the umbrella of Uncommon Files. However, if it’s another file type, it might not open with one of the programs listed above. Take the following steps to find the file type:

  1. Right-click the file.
  2. Click “Properties” (Windows) or “More Info” (Mac).
  3. Locate the file type under either “Type of File” (Windows) or “Kind” (Mac).

3rd Method: Check with the developer.

Even if these methods were unsuccessful, you might still be able to reach out to a software developer for help.
