This video explains how you can link an Microsoft Access table to a delimited text file. When you link the file to a table MS Access creates a linked table and establishes a link to the text file, the data still lives in delimited text file. Any changes made to the data in text file will be reflected in the linked table when you see the data from MS Access datasheet view. You can not change data from MS Access and if you try to change data MS Access displays error.
