I find Hex Editors incredibly useful - "Frhed" is never more than a right click away - for revealing all sorts of information within files. Indeed, it's my default viewer for unknown files. The trouble is once "they" start encrypting the files (as opposed to compressing) you are screwed. More exactly, they have screwed you. Hex editors are really only of value if the values are in a straight format. If you don't have (or want) hex there's always Microsoft Office and VBA. A few lines of code is all that's needed to hex-dump right into a speadsheet. On top of that once you've worked out what's in the file - or where it is / how to find it - you're free to collect the info where you want it. Which is precisely why they are starting to encrypt everything. Because then you will have to pay/licence the tools to use your own images. :o) Bob Hex editors for the Mac? Excel?
