NAME         top

       mysql_fix_extensions - normalize table file name extensions

SYNOPSIS         top

       mysql_fix_extensions data_dir

DESCRIPTION         top

       mysql_fix_extensions converts the extensions for MyISAM (or ISAM)
       table files to their canonical forms. It looks for files with
       extensions matching any lettercase variant of .frm, .myd, .myi,
       .isd, and .ism and renames them to have extensions of .frm, .MYD,
       .MYI, .ISD, and .ISM, respectively. This can be useful after
       transferring the files from a system with case-insensitive file
       names (such as Windows) to a system with case-sensitive file

       Invoke mysql_fix_extensions like this, where data_dir is the path
       name to the MySQL data directory.

           shell> mysql_fix_extensions data_dir
