binary-extensions

Curated list of binary file extensions for text/binary classification.

This crate exposes one immutable list of 262 file extensions commonly associated with binary files: archives, images, audio, video, office documents, executables, fonts, RAW camera formats, and similar. It carries no logic and no runtime dependencies.

Classification by extension is a heuristic. A few entries (for example rtf, m3u, slk) are text-encoded formats kept for compatibility, so membership does not prove a file holds binary bytes.

Installation

[dependencies]
binary-extensions = "0.1"

Usage

use binary_extensions::BINARY_EXTENSIONS;

assert!(BINARY_EXTENSIONS.contains(&"png"));
assert!(!BINARY_EXTENSIONS.contains(&"txt"));

binary_extensions::all() returns the same slice if you prefer a function call.

Entries are bare tokens without a leading dot, for example "png", never ".png". Strip the dot and lowercase a path extension before checking membership, otherwise names like IMAGE.PNG are missed. Every entry is lowercase except "DS_Store", the macOS Finder metadata file, whose casing is preserved and matched as is.
