if the amount of data is not astronomic and if your are in possision of MSOffice you can consider another solution (that gives more control).
1)Read the text-data into Excel
2)Save as excel-datafile (.xls)
3) Create an empty database i MySQL using Sqlyog
4) Open the excel-datafile from Access
5) Export from Access via ODBC to Mysql
6) Correct tabledefinitions if necessary (for instance Mysql has much more text-types than Access) using sqlyog.
7) Create the indexes that you need and perhaps a primary key using sqlyog.
