\fBmysql_fix_extensions\fR
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\&.
.PP
Invoke
\fBmysql_fix_extensions\fR
like this, where
\fIdata_dir\fR
is the path name to the MySQL data directory\&.
