A .BMK file generally stores pointers to saved spots for things like document pages, media timestamps, or saved locations inside an application, but with no standardized `.bmk` format, each program writes its own structure containing labels, titles, page references, timecodes, file paths, IDs, or coordinate/zoom info; some BMKs show readable text when opened in Notepad, while binary ones don’t, and they’re used for PDF/eBook bookmarks, audio/video markers, CAD/map views, and resume features, identifiable by checking which app folder they appear in and whether the contents are readable.

To figure out what a .BMK file is, the first step is learning what created it and whether it’s text-based or binary, so start by checking where it lives—folders tied to a certain program, AppData/ProgramData, or sitting beside a PDF/video often reveal what it belongs to—then open Properties to confirm the extension and see if “Opens with” points anywhere, and try Notepad/Notepad++ to check for readable text like titles, page numbers, timestamps, or structured tags, which means it’s a text bookmark, while gibberish indicates a binary file that must be opened through its original software, and companion files with matching names usually show exactly what content the BMK references.

A .BMK file won’t tell you its purpose just from `.bmk` since multiple programs use `.bmk` differently, so the goal is tracing it back to its source application; look at where it resides, what Windows says under “Opens with,” and how it appears in Notepad—clear text such as URLs, timestamps, or structured markup indicates a readable bookmark list, while unreadable characters imply a binary, app-specific format that typically requires the original software.

Once you know the .BMK type, you know exactly what workflow to use, because text-based BMKs open best in Notepad++, where you can read titles, pages, timestamps, and references before converting them into `.txt`, `.csv`, or URL-based bookmark lists, whereas binary BMKs must be processed inside the original software using features like Import Bookmarks or Restore Session to export into standard formats, and if the source remains unknown, examining its folder context and any readable strings usually reveals the application and proper export path.

A “bookmark file” acts as a collection of saved jumps telling software where to return later, usually including a label and a target like page numbers, timecodes, headings, or positional data, and when the content reopens the app restores these as bookmarks or resume points, but because the BMK only contains references and not the content itself, it becomes useless if the original file is moved, renamed, or missing.
