Restoring database files
I have a mysql database , which tables are archived and i remove some files (montly data, .frm .MYD, .MYI) from the servers disk to an external storage. And i also drop or flush these tables from phpmyadmin. If i need to look and query these offline mysql files what i need to do after copying the files back to the mysql path of the server?

If i need to look and query these offline mysql files what i need to do after copying the files back to the mysql path of the server? which query? * stop mysqld * copy back the files * start mysqld MyISAM tables and databases are simply plain files and folders including the database mysql which can be copied since mysql# exists without needing any magical command signature.asc Description: OpenPGP digital signature
