Extended File Attribute Editor is a desktop file property browser, Linux user.* extended attribute editor, and binary header metadata reader for Linux systems. An independent Linux alternative to file property and extended metadata utilities such as PropertySystemView, getfattr, and setfattr, it inspects POSIX inode records, edits user.* extended attributes on supported filesystems, and parses embedded container headers directly from disk.

Key Features:

• Live Extended File Attributes (xattr): Reads, adds, updates, and deletes user.* namespace attributes (such as user.comment, user.tags, user.category, and xdg.origin.url) via native Linux xattr system calls with clean handling for filesystems that do not enable extended attributes.
• POSIX Inode & Stat Inspector: Displays full inode number, octal and symbolic mode bits, link counts, resolved owner UID/GID names, allocated 512-byte blocks, and high-precision access, modification, and metadata change timestamps.
• Pure-Python Binary Header Reader: Extracts embedded metadata from PNG (IHDR, pHYs, tEXt, iTXt), JPEG (JFIF, EXIF IFD0, SOF dimensions), PDF (/Info dictionary), MP3 (ID3v2 text frames), ELF executables (64/32-bit class, ABI, machine type), and ZIP archives without external helper processes.
• Batch Tagging & Structured Export: Applies or removes user.* attribute tags across multiple selected files and exports complete property tables to CSV and JSON.
