Opening a file without extension
If you notice a file without extension, you can still use the signature of a file to identify the file type. All known file types have a standarad signature this signature is stored in the file itself. There are many tools available which can determine the signature of a file even if the extension is missing and one of the best tool to do so is File Identifier.
File identifier lets you easily identify different file formats and also allows you to extract metadata from some file formats. After identifying the file type you can use Wolfram alpha to know which software can be used to open that file.
