If there is only textual information with no graphic objects, then a minimum of two files is needed: *.TAB and *.DAT. Basic file set for viewing data and its graphic representation in vector form within Mapinfo Professional requires a minimum of four files, normally the *.TAB, *.MAP, *.DAT and *.ID



.TAB (The ASCII file that is the link between all other files and holds information about the type of data set file )
.DAT (The file that stores the attribute data. This a dBase III DBF file (http://en.wikipedia.org/wiki/Dbf#File_formats)).As an alternative to the *.DAT file, MapInfo Professional can use other data formats such as, *.TXT, *.XLS *.WK*, *.MDB (and for each Micosoft Access format the software also makes another small file). MapInfo Professional still creates a .TAB file that contains information about the data set file, and the user interacts with the TAB file only.



.MAP (Stores the graphic and geographic information needed to display each vector feature on a map)
.ID (Stores information linking graphic data to the database information. This contains a 4-byte integer index into the MAP file for each feature).
.IND (Optional index file for tabular data. This is present if any columns are indexed).

For more, refer to http://en.wikipedia.org/wiki/MapInfo_TAB_format

You can use mi to read it and convert by export function.
