collabora_cannot_be_opened.doc (9.3 MB)
As shown in the attached doc document, this document can be opened by Office but cannot be opened by LibreOffice,and cool cannot be open.

The file is indeed a valid legacy .doc format (OLE2 / CDF V2), created in Microsoft Word on Windows.

Key details:

  • File format: Composite Document File V2 Document
  • Code page: 936 → Simplified Chinese (GB2312)
  • Created with: Microsoft Office Word
  • Last saved by: ideal gu
  • Pages: 10

Run command file collabora_cannot_be_opened.doc

What This Confirms

  • Not corrupted at the container level — the structure is readable
  • Microsoft Office opens it fine because it supports all legacy formats with localized encoding
  • LibreOffice & Collabora fail because:
    • the file likely contains non-UTF encodings (Code Page 936) or
    • uses special embedded objects or fonts unsupported by LibreOffice

Re-save as .docx in MS Word

Since Word opens it:

  1. Open the file in Microsoft Word
  2. Use Save As → Word Document (*.docx)
  3. Try opening the new .docx in:
  • LibreOffice Desktop
  • Collabora Online

This usually solves compatibility and encoding issues.
