TrID

TrID is a powerful command-line utility that analyzes the binary structure of any file to determine its true format, revealing the correct file extension regardless of its name. Using an extensive and continuously updated definitions database, it reads and interprets raw file data to provide accurate identification across thousands of file formats. Compatible with both Windows and Linux systems, TrID offers reliable file type detection for digital forensics, data recovery, and system administration tasks where file extensions may be missing, corrupted, or deliberately misleading.
