Doc files relate to Microsoft Word and virtually all office programs (From any manufacture) can open them, as over the years they have pretty much become the world standard for office documents.
To convert them to text, (Note you will lose all the formatting and special features) open them in any Word processor (Open Office is a free one if you don’t have the common Microsoft Word) then choose the Save As option from the file menu, when the save box opens look for the box (It will normally be a drop down menu) that allows you to choose how to save it, select the Text option, click save and you are done.
NOTE: just changing the extension from doc to txt will not work, as you will just get garbled results. (If you want to view the extensions select the Tools menu (In any Windows explorer box (Not Internet Explorer) and choose folder options followed by the view tab, there you will find the option to display them.
NOTE: Your keyboard may require you to change the text to a font that it understands
Hope this helps
Bill
