Sometimes you might get stuck with files without extensions and windows will be showing them as unknown files.If you get a lot of attachments in your emails, you’ll know what I am talking about.In this case you might have tried your luck renaming those files to .txt or .zip, but in vain.
There is a small application which does this job for you.It identifies file extensions by checking the binary signatures of the files.
TrID is a small application which helps to find the actual extension of unknown files.This software is designed to identify file types from their binary signatures.You can download the GUI version of TrID and in the application browse to the file you want to analyze.Double clicking on any item shows additional information like the definition’s file name, its author & e-mail address (if provided), a clickable link to a reference URL, remarks, etc.
You can also download the command line version of this tool from here.
If you are having a group of unknown files in a folder,wildcards could be used to scan all the files in that particular folder.In addition, using the switch -ae will instruct TrID to add the guessed extensions to the filenames. This come handy, for example, when working with files recovered by data rescue softwares. For example:
Now the files in the c:temp folder will look like:
