Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited support for non-standard file types

   Relies on libmagic, which may not recognize less common or proprietary file formats.

2. 02

   Performance overhead when processing large files

   Analyzing the content of very large files can be slow and resource-intensive.

3. 03

   Depends on libmagic, which may not be up-to-date with new file types

   libmagic signatures are updated periodically, potentially missing newer or less common file formats.

4. 04

   Configuration complexity for custom magic files

   Setting up and maintaining custom magic files requires detailed knowledge of the libmagic format and structure.

What it does well

• Identifies file types based on content, not just filename extensions.

• Wraps the libmagic library for easy integration into Python projects.

• Supports a wide range of file formats and signatures.
