One of our clients has a CD with documents she said the secretary before her used to use. These files will not open with either Microsoft Word or Corel WordPerect in any file type I try to use. The format of the file name is "E####*.CFS *". # being a number, * being either a character or sequence of characters or words. Sometimes it's just "E####.CFS *". Very strange file. I'm thinking it might be some form of encrypted file at this point.

I'm a bit confused. you seem to indicate that the file extension is: .CFS * I've never seen a file extension with a space followed by other characters. Am I reading your post incorrectly? BTW...A Google search of the CFS extention returns one hit for a ChatFactory Script, but I doubt that's what your looking for. www.chatfactory.net

It's a document. I realize it doesn't really make sense but the fact that all files follow that naming format forces me to assume it's a CFS format of some sort. Oh and believe me, I've been searching Google for a while. Maybe it's some old word processor's file format. These files date from 1995-2001. Of course, no one at the office knows anything about it. The files "just worked".

I'm wondering if it isn't a file split up into multiple smaller files. I know you can do this with WinZip or WinRAR for example, but neither of those use a CFS extension. If you try opening the file in notepad (or wordpad) can you make out sentences or is it just gibberish? -Ryan Adams http://RyanTAdams.com

I would think the client would know what these files are and what program was used. Why not ask your client to contact the former secretary? Did you look here? http://filext.com/file-extension/cfs Life's more painless for the brainless.

OK, maybe the more relevant question is this: What do you need them for? They're 6+ year old files that no one knows anything about. Why do you need to open them?

Very good point. Life's more painless for the brainless.
