A .BMK file serves as a marker for stored locations but varies widely because `.bmk` has no universal format, so different programs embed items like labels, titles, page indices, timestamps, file paths, or coordinate data in their own way; some BMKs are plain text—readable in Notepad—while others are binary and appear as gibberish, commonly used for document bookmarks, multimedia time markers, CAD/map saved views, or app resume points, and you can usually figure out which type you have by examining where it was found and whether its text opens cleanly.

To figure out what a .BMK file is, start by seeing which app it’s tied to and check whether it’s plain text or binary, so examine its location—software folders, AppData/ProgramData, or alongside PDFs/videos—to narrow down the creator, view Properties to confirm details, and open it in Notepad: if you see readable text like URLs, titles, page references, or timecodes, it’s a text bookmark; if it shows random characters, it’s binary and meant for the original application, and nearby companion files with the same base name usually reveal the content it references.

A .BMK file is used by various apps in incompatible ways which means the only way to know what type you have is to find the program that made it; the strongest clues come from the folder it’s in, Windows’ association, and whether Notepad reveals readable items like page numbers, paths, or labeled markers—gibberish means it’s binary and must be used through its native application.

Once you know the .BMK type, you can immediately decide how to handle it, 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" is basically a small helper file that remembers shortcuts to specific spots so you don’t have to search for them again, meaning it stores things like titles you typed plus targets such as page numbers, timestamps, headings, scroll positions, or map coordinates, and when you reopen the related content the app reads the BMK to rebuild your saved locations—appearing as bookmark lists, timeline markers, favorites, or resume points—which is why the BMK is useless alone and needs the original file, since it holds navigation memory rather than the content itself.
