An ASX file functions as a pointer-style media list that tells a player where to find the actual media via `` pointers to web-hosted files, and may arrange several linked items so they play back in order as a simple playlist.
ASX files often attach descriptive info like titles or authors so players don’t display raw URLs, and may contain playback hints or older extras such as banners—even if not all players use them; historically they spread because websites and broadcasters needed a reliable click-to-play method for Windows Media Player that supported live streams, fallback URLs, and behind-the-scenes endpoint changes, and today the easiest way to understand an ASX is to open it in Notepad and inspect the `href` targets that show where the real media lives.
To open an ASX file, remember it’s not the media itself that forwards playback to another location, so choose a player that reads its references; the most reliable Windows option is to right-click the `.asx`, choose Open with, select VLC, and let VLC chase the URL targets, while Windows Media Player—although originally intended for ASX—can fail with outdated protocols or codecs no longer supported.
If playback doesn’t begin or you want to confirm the media target, just open it in a text editor and look for ``; that `href` text is the true stream or file path you can paste into VLC’s Open Network Stream or a browser if it’s an `http(s)` file, and when multiple refs exist it functions like a playlist so you can try another entry, while outdated `mms://` addresses may fail in modern players, making VLC testing the fastest check and consistent failure usually indicating a dead or restricted stream rather than an ASX issue.
If you have an ASX file and want to figure out its actual target, just open it in Notepad, search for `href=`, and locate lines such as ``, where the quoted value is the real destination; multiple entries imply playlist/fallback logic, and while `http(s)` links are standard modern URLs, `mms://` streams are legacy-style and may only resolve reliably when pasted into VLC’s Open Network Stream.
You may find network-share paths such as `C:\...` or `\\server\share\...
