Playlist Synchronisation for Portable Devices
I have recently been attempting to properly set up synchronisation between Windows Media Player and my portable music player (which happens to be my phone). Though I found that the Windows Media Player synchronisation tool does the job pretty well, it does fail in one respect: it cannot copy over playlist (WPL) files. For me, this was a bit of a nuisance, since I rely very much on playlists to categorise my music collection.
The solution for me was to write my own tool that synchronises a given set of playlists with a portable device that is compatible with WMP (Windows Media Player) – as I believe many devices tend to be. The tool works simply by finding the appropiate place on the device to which to copy the playlist files (a known XML descriptor file on the device should specify this), and then copying over these files, with the locations of the media files updated to point to those on the device.
Naturally, my choice of technology with which to write the thing was .NET/C# – this does mean that it’s not a fully standalone application, though it does only consist of a single EXE. However, thanks to a few particularly convenient features of the language/framework (primarily LINQ to XML), the code was largely trivial to write, and the majority of the ~200 lines is in fact error handling.
You can download the program here. As mentioned, it requires the Microsoft .NET Framework 3.5 (SP1) to run, which is not installed on any current version of Windows by default, so it will need to be downloaded and installed firstly if you don’t yet have it. Also, if anyone is curious to see the code, I may be able to upload that at some point.
The tool should be run from the command line, and would seem to be very straightforward to use. (Run the program with no arguments to see the help information.) An example command line to syncrhonise the playlists in the standard location of your user profile with a portable device on drive F might be:
pps F “C:\Users\username\Music\Playlists”
That’s all it takes. The task should finish within a matter of seconds and then report some general information about the playlists it found and what it managed to successfully synchronised; else return an error message.
NB: If you’re wondering how the synchroniser matches the media files on the device with those in the playlist, I have a small admission to make. Because the directory structure is not guaranteed to be the same on the device as at the location of the source media, the current version simply matches media items by file name. This works perfectly well for me, though there is clearly a caveat. I am looking for an improvement on this method, and while I have a few ideas, I haven’t finalised my decision yet. Any recommendations by someone more knowledgeable on the subject would be appreciated.
Now, this program was designed primarily for my own use, but I did consciously attempt to make it usable with any WMP-compatible portable device, so hopefully people shouldn’t have any major problems using it.
Finally, it would be nice to hear any feedback regarding this little tool of mine, so please feel free to drop me a message (even if it’s just to say you’re using it). If I hear any suggestion for a worthwhile feature to add (or of course a valid bug report), I will gladly update the program.
