How to restore SQL database with .frm, .MYI, .MYD, .opt files?

Question

MySQL

here are the rest of the files from the database. at least restore the structure and relationships between tables, I'm not talking about the data itself

Answer 1

there is such suffering, but in general Google can do a lot of gitik (c)

Answer 2

Judging by the screenshot, you have a MyISAM engine. In this case, each table is stored in 3 files:
.frm is the structure of the table
.MYD - data
.MYI - indexes
In principle, to restore such a database, it is enough to copy these files to the database folder and restart mysql.
