Enviroment Variable (no replies)

History – HD crashed. New HD. Had to reinstall all programs.
Hardware:
Laptop 16 GB of RAM 1TB HD Core i7 processor
Windows 10 64
MySQL 5.7 Development Enviroment
Using Workbench and SQLyog programs
Main tables are large - 3 to 4 M rows
Problems:
Size of file lock table – added entry in my.ini set it at 8G. Put the my.ini in both the root and bin directory (is this correct)?
Now lose connection after 30 sec on table updates touching each row. Problem with both Workbench and SQLyog. What is the problem and solution?
Thanks
Dave
