FileX

FileX is an efficient software which can help in identifying the type of file without any extension or file type identifiers. It is a free application that relies on the Unix command-line utility file to assist you in the process. The software is particularly useful when working with suspicious email attachments, where the file type is unknown.

The application uses complex algorithms to analyse the file and offer accurate results based on the information of a file called magicfile. The results obtained by FileX are displayed in the program window, and the software also displays the MIME type of the file. Users can conveniently copy or drag the displayed information to any other application or document.

To obtain file analysis, users can follow three simple methods. They can drag the suspect file onto FileX icon or the program window for analysis or use the "Open…" command in the "File" menu. However, the technicalities of the command-line file utility determine the reliability of the application. The accuracy of the results relies on the accuracy of the command-line file utility.

FileX also offers additional features, such as displaying the information about the original file when a soft-link or alias is dropped onto the software, and can only display the file information about the first file when multiple files are dropped onto the software.

For more information about FileX, users can consult its man page. However, one limitation is that the accuracy of information about new formats is not precise in the version included in Mac OS X. Overall, FileX is an efficient software, which offers accurate file-type identification, improved productivity, and convenient file-management features.
