MIME File Type Explorer

MIME File Type Explorer is a desktop Freedesktop Shared-MIME-Info database
browser, desktop handler viewer, and live file magic-byte header inspector for
Linux. An independent Linux alternative inspired by file type management utilities
such as FileTypesMan, it parses the system /usr/share/mime database and desktop
application caches to inspect registered media types and verify real files on disk.

Key Features:
- Full Shared-MIME-Info Registry Browser: Parses /usr/share/mime/{types,globs2,
aliases,subclasses,generic-icons,magic} across 1,000+ registered MIME types
spanning application, audio, font, image, model, multipart, text, and video.
- Subclass Hierarchy & Desktop Handlers: Displays parent MIME inheritance chains,
alias mappings, generic icon names, XML type descriptions, and associated
.desktop handlers from mimeinfo.cache and user mimeapps.list.
- Live File Magic-Byte vs Extension Inspector: Reads real files and folders to
compare filename-extension MIME inference against binary MIME-Magic header
signatures, flagging mismatched or extensionless files with a 128-byte hex dump.
- Category Analytics & Reports: Renders a media-category distribution chart and
exports full MIME catalogs and file inspection results to CSV and JSON.
