Information about the .myi (myi) file type

Below is all the information we have available on file about the .myi (myi) file type.

.myi
MySQL index file. Contains indexes for a MySQL database table, it may also contain some statistics about the table.

Along with each .myi file there should be a .frm file (containing the table structure) and a .myd file (containing row data).

Where this is available we would like to include file format information on .myi files, as well as information on how to view or open files of type .myi. If you know of any information which we have missed then please let us know.
