.BK is a System / misc file (System & disk). Analyser identifies a .BK file and reads the metadata in its header, right in your browser. Analyser handles .BK alongside related formats such as .OPML, .RSS, .ATOM and more. In Analyser's format library, .BK sits in the System & disk category. Analyser recognises .BK files from their contents and reads what metadata it can - entirely on your device, with nothing uploaded.

How do I open a .BK file?

Drop a .BK file onto Analyser at https://lab.valjdakosta.com/ and it is identified directly in your browser - no upload, no account and no software to install. Inspect OS and system files: OPML subscription lists, RSS/Atom feeds, Linux .desktop launchers and systemd .service units, Apple .crash reports, Android .ab backups, Windows Task Scheduler .job, Group Policy Registry.pol, and .scr screensaver PE headers, plus identification of .DS_Store, Thumbs.db, dSYM/DWARF and shim .sdb. Scene .nfo ASCII art now opens in a CP437 viewer - see Text art above.

Can I open a .BK file online for free?

Yes. Analyser is a free online .BK identifier that runs entirely in your browser - your .BK file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.
