What to expect

  • Word-specific features and macros are not preserved.
  • For long-term or shareable use, ODT or DOCX retain far more than SDW.

Frequently asked questions

How faithful is a DOC to SDW conversion?
SDW is an obsolete StarWriter binary format, so converting a Word document into it targets a legacy word processor. Modern formatting features may be simplified or lost when written to the older format.
Why would I convert a DOC to SDW?
Mainly for compatibility with very old StarOffice/StarWriter software. For general or archival use, ODT or DOCX are the practical choices.
What can open an SDW file?
LibreOffice Writer can read SDW on all platforms, but few modern programs support it, and Microsoft Word does not open it directly.
What are the caveats of targeting SDW?
Because SDW predates modern Office features, complex layouts and any macros will not carry over reliably. It is a legacy target, not a good long-term storage format.
