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.
