mysql_fix_extensions - normalize table file name extensions
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 names.
Invoke mysql_fix_extensions like this, where data_dir is the path name
to the MySQL data directory.
shell> mysql_fix_extensions data_dir
