An ASX file acts as a metadata-based media launcher rather than a media container, supplying directions that tell your player where the true audio or video resides via `` tags linking to web URLs, and can include several entries in order so the player loads each stream or file in sequence.

ASX files commonly embed lightweight metadata such as titles or authors instead of exposing plain URLs, along with optional playback cues or legacy features not always honored by modern players; they became popular as a simple way for websites and broadcasters to trigger Windows Media Player, handle live streams, supply fallback links, and swap out real endpoints without changing the public link, and now the quickest way to see what an ASX does is to open it in a text editor and read the `href` entries that reveal the true media source.

To open an ASX file, treat it as a playlist of pointers rather than a media file, so you open it using a player that can interpret its links; on Windows, the usual method is right-clicking the `.asx`, selecting Open with → VLC, letting VLC follow the URLs, and though Windows Media Player may handle some ASX files, it can run into trouble with legacy streaming protocols or unsupported codecs.

If playback won’t start or you want to examine its linked source, open the ASX in Notepad and find ``; that `href` text is the real stream/file you can paste into VLC or into a browser if it’s an `http(s)` location, and when multiple entries exist it operates like a playlist so one may succeed if another fails; older `mms://` links often don’t work in modern players, so VLC testing is the quickest check, and persistent failure usually means the stream itself is dead or legacy-dependent, not that the ASX is wrong.

If you have an ASX file and want to see what stream it actually references, open it in Notepad and look for `href=` within `` tags, since the attribute value is the real playback destination; if multiple `` tags exist, the file provides playlist or fallback options, and while `http(s)` links are modern, `mms://` URLs are older and may need to be tried in VLC’s Open Network Stream.

You may sometimes notice local filesystem links like `C:\...` or `\\server\share\...
