Or Notepad, or Wordpad .. what you are doing is Copying the contents of the Word document, and Pasting them into an editor which doesn't understand Word's style and format information and only accepts the raw characters. Which is all that you are interested in. I don't think it's entirely reasonable from your users' point of view to only be able to deal with plain text files, though; for example, what about images? (.jpg, etc) which are going to give you the same problem. Perhaps you could consider reading the files using Ada.Streams.Stream_IO? Example use in procedure Output_Contents starting at line 182 of http://goo.gl/wcqkop

Many thanks Simon,

I think I will leave images for the present - just security of information will be all for now - frankly I dont know enough about images yet but anything that can be reduced to an alpahnumeric can be encrypted by my cipher.

Can I come back to you sometime in the future on this one.
