Got following error in 5.7.19 on Windows 7:

Searched and found exact error in 8.0 DOC:


But could not find same thing in 5.7 DOC:


How to repeat:
See description.

Suggested fix:
Add same error strings into 5.7 DOC as well for clarity.

Cannot Open Data File content was added to the MySQL 5.7 manual. 

The change should appear online soon.
Thank you for the bug report.
