A .CLPI file is essentially a playback-info file for Blu-ray clips, found in BDMV/CLIPINF and paired with a matching .m2ts under BDMV/STREAM; it lists available streams and timing information for accurate seeking, so most apps can’t "open" it meaningfully, and proper viewing requires launching the Blu-ray index or using the correct .mpls playlist, because the .m2ts files contain the real media and may be arranged in segments that don’t play correctly on their own.

A .CLPI file serves as the detailed metadata for a Blu-ray clip, listing every elementary stream in the associated .m2ts along with codec types and PID/stream IDs, and providing timing plus navigation data so the player can seek accurately, sync audio/video, and perform seamless branching without gaps, defining both which streams exist and how the timeline relates to file positions.
A Blu-ray usually contains many `.CLPI` files because each `.m2ts` clip in BDMV/STREAM has a corresponding `.clpi` in BDMV/CLIPINF, and discs include numerous segments such as menus, logos, warnings, trailers, supplemental content, and branching-specific pieces; playlist assembly and seamless branching further increase clip counts, so a full CLIPINF folder simply means the movie is built from modular clips requiring their own playback metadata.
A .CLPI file won’t open like a normal video or document since it’s purely a
Blu-ray metadata/index file, so double-clicking brings up app prompts or random characters in a text editor, and even Blu-ray software doesn’t "play" CLPI files because they only inform the engine about streams and timing while playlists handle the actual sequence; only diagnostic Blu-ray utilities meaningfully parse CLPI, and to watch the movie you should use the BDMV index or the correct `.mpls` playlist.
A .CLPI file provides the low-level rules for playback, describing which streams are in the associated .m2ts and how they’re identified, plus the timing/seek mapping needed for accurate jumps, A/V sync, and track changes; it becomes vital when .mpls playlists assemble multiple clips or when seamless branching chooses alternate segments, meaning the CLPI is what allows the Blu-ray system to stitch clips together and navigate without glitches.
A `.CLPI` file is interpretable only by checking its neighbors, because while Blu-ray uses `.clpi` for clip metadata, other systems may repurpose the extension; if you see a `BDMV` folder with `.m2ts` and `.mpls`, it’s standard Blu-ray and you must use the entry or playlist to watch content, but in folders lacking that structure—like console/game dumps—it might be proprietary metadata instead, and an extracted CLPI alone is useless without its matching streams and playlists, making nearby files the key to determining its role.
