Export to DBASE III

I need to export ms access table to dbase III format.
When I use export something is missing and the file format
is just not good.When I try to open dbf file with
program Dbase I get message "not a dbase database".
I find out that excel do the same, so if anybody know
how to export to dbase III using ms access or ms excel
please help.Ms access help is to install borland database,
I downloaded some from Internet but I don't know what to do with it.
PS: Even when I import dbase III file and try to export it back
there is a problem. Import is good, but export fails.
Please, please help.
