I couldn’t open “World Brumand. docs” file from Microsoft word

If the file name is exactly as you posted here, there's a space between the period and docs, which can't be there. And that's just one issue with the file name. The other is Word has no such extension as docs. It's either doc for older version of Word files, or docx for any native format document of Word 2011 or later.

Perhaps the file is corrupt. What is the exact error message you get when you try? Do you have a copy of Microsoft Word, or a suitable viewer?
