Having typed a piece of info to keep for reference, and saved in probably notepad or word pad, I now find I am unable to open what is described in properties as a 'dex' file.unknown application shown ikon those little red,green and blue dots.I have no idea how this comes into being. How do I open this file. I have tried the usual alternatives. Can anyone help please?
Sorry had to go away,thanks for the responses. OK I renamed the file 'DEX.txt' and tried to open and got a banner saying "This file does not have a program associated with it for performing this action.Create an association in the Folder Options control panel" but I am unclear how to proceed.
