More than 400 SQL files, how to import into MySQL

More than 400 SQL files, how to import into MySQL?
I am using phpMyAdmin now, as if other people also use this software to back up the thing, how do I restore? Wouldn't it be a one-off restore? Each file has a size of 2m

------Solution--------------------
Write a batch processing tool. How often does the scheduled task import a file.
------Solution--------------------
Import databases directly

See a way to try it:

The Source.sql file reads:
SOURCE C:/sql/1.sql;
SOURCE C:/sql/2.sql;
SOURCE C:/sql/3.sql;
....

then source Source.sql;
Never tried.
