A .BMK file usually represents a bookmark-style reference that stores jump-back locations like pages, timestamps, or saved items, but because `.bmk` isn’t a universal standard, each program uses its own format, meaning a BMK might hold labels, titles, page numbers, timestamps, file paths, IDs, or map/CAD coordinates; some are text-based and show readable URLs or titles in Notepad, while others are binary and look like gibberish, being used for things like PDF/eBook bookmarks, media time markers, CAD/map views, or resume points, and the best way to identify yours is checking where it came from and whether its contents open cleanly in a text editor.

To figure out what a .BMK file is, you start by learning its source and whether it’s readable text or app-specific binary, so inspect the folder it’s in—program directories, AppData, project folders, or files next to PDFs/videos often reveal its purpose—check Properties for clues like "Opens with," then try viewing it in Notepad to see if it contains readable entries (titles, page refs, timestamps, or structured data), which means it’s a text-based bookmark, while random symbols imply a binary format meant for the original program, and similarly named nearby files often reveal what document or media the BMK links to.

A .BMK file varies depending on the software that created it, so determining its exact type requires discovering the generating app and examining its structure; check its storage location, the "Opens with" field, and how it looks in a text editor—if readable elements like URLs, timestamps, or structured text appear, it’s a text-based bookmark, but if it shows random symbols, it’s a binary format usable only through the program that originally produced it.

Once you know the .BMK type, your workflow depends on that, with text-based BMKs easily opened in Notepad++ for safe viewing so you can convert them into `.txt`, `.csv`, or URL bookmark formats, while binary BMKs require their parent application to load bookmarks/markers and then export to formats like XML, CSV, or cue lists, and if you lack source info, identifying the app by folder context and readable embedded text is usually the key to unlocking conversion options.

A "bookmark file" works as a tiny index of saved locations designed so the application can revisit exact positions—whether pages, timestamps, headings, scroll coordinates, or mapping locations—by reading the bookmark names and targets you stored, rebuilding them into bookmark lists or resume markers when the original content opens, and since it contains no actual document or media, it depends entirely on the original file to function properly.
