Microsoft Notepad
 

I am running office 2003 and recently I have been receiving documents that i am unable to open. It seems they are in "Notepad" formate. I am familiar with Word and Excell but not Notepad. I have googled it, but still unable to find out anything or how to download it if I need to.

I know someone here has the correct answer, so what do I need to do to be able to open something that is in Notepad format.

Thanks in advance of helping me out.

Are these documents by chance in .docx format? If they are, check this out:

If not, can you let us know the extension these files are in? Are they .txt? .rtf?

Baraka is probably right. They're most likely .docx files which are Office 2007 and forward. That link will help you if that's the case.
