This extension has been used by more than one format

2 different formats have claimed .scd over the years, so two files with the same extension aren't necessarily the same kind of thing.

How to open a .scd file

  • Try LibreOffice (free, Windows/Mac/Linux) — it opens an enormous range of current and historic document formats.
  • Microsoft Word and Google Docs handle most mainstream document types.
  • If nothing opens it, open it in a text editor: many older document formats have readable text inside.

The registry records this extension against Schedule+ Contacts, Scribus Document, so software from that family is the most likely match.

How to convert a .scd file

  • Once it opens in LibreOffice or Word, Save As .docx or .pdf to get it into a format you can use anywhere.

MIME type

When a .scd file travels over the web, servers label it with this MIME type:

application/vnd.scribus
