A definite improvement over the last version of listext, especially with regard to file locations!

In my case, I have many thousands of extensionless files. By reading the file headers, there are a variety of file types, mostly audio, imagery with some video as well.

Ultimately, I would like to see the option of being able to read extensionless files to determine their file types and then determine the appropriate compression methods to be used.

I'm fairly new, but I use a free application built by the British National Archives called DROID (Digital Record Object IDentification).

It's a very simple tool that uses signature files to detect file formats. It's not perfect (for example, I have quite a few mp4s it won't detect and have recently submitted a request for them to update their mp4 signature), but it's able to return data for most of my files and it's always accurate (in my experience) when it specifies the format.

I threw a bunch of files in a folder and scanned them so you can see the output.



As you can see, it found most files and even looks inside a non-password protected archive to give info on contained files as well.

DROID can be downloaded directly from the UK National Archives site:

Another application called TrID. It uses an algorithm to find similarities between files in order to determine filetype as opposed to looking for specific hard-coded headers. It's available as a command-line application:

or with a GUI:

I hope these are helpful for you.
