You guys ever hear of a .btw file?

[BrianG]

I just looked up the BTW file extension and it says that it is a label used with the BarTender program. It also says it can contain text, graphics, etc, so it makes sense that you could read part of it (the text part), but the embedded graphics would appear as gibberish.

This is a lot like the older MS Word files (prior to "docx" where they are now compressed XML files) where the you could see the text, but all the formatting and any embeds would appear as gibberish.
