I'm writing a Python function to detect file formats based on their magic bytes. For most formats in file compression , identifying the magic bytes is straightforward. However, I'm uncertain about TAR files. Do TAR files have a specific magic byte for detection? From what I understand, TAR files may contain the string "ustar" in their header, but I'm not sure if this qualifies as a magic byte. Additionally, how should I approach detecting compressed TAR files, such as .tar.gz or .tar.bz2? Should I first check for the compression format and then confirm the TAR structure? Any advice or examples would be appreciated. Thanks in advance! Continue reading...
