I needed to figure that out today, the third day in a row I had bizarre file format questions. And no, I don’t mean .asf the windows streaming media format. In this case it turned out to be a binary file type from a dos-based statistics package. An emeritus faculty member had brought it in and wanted to print. I figured out how to manage this after stumbling across filext, a website devoted to cataloging all known file extensions. It’s got a pretty impressive database of filetype, including my unknown ~15 year old dos file. I wonder how long it will be until digital forensics becomes part of the curriculum in archaeology courses, clearly the need for the skillset will be there. Anyway stash a bookmark to filext away, it’s definitely a very handy site.
