Here is my official snippet of how to use and scenarios that may warrant the use of this program.
Problem1: You have several great playlists on your Desktop PC, but dread having to recreate them all on your CarPC.
Solution1: Use PlaylistConverter to transfer and, if necessary, convert your playlists along with all of the related music files directly to any folder on your CarPC.
Problem2: You don’t have enough HDD space on your CarPC for all of your music, but don’t feel like manually separating and copying part of your collection.
Solution2: Use PlaylistConverter, and selectively transfer only the music from the playlists that you want.
Problem3: I hate creating playlists on that TINY SCREEN!
Solution3: Create playlists on your Desktop PC, and then easily transfer them and the related music to your CarPC.
This program will transfer your iTunes, Windows Media Player, or Winamp Playlists from your Desktop PC to your CarPC. This way you do not have to manually recreate all of your favorite playlists on your CarPC.
It will convert non-standard playlist files such as .txt or .asx into standard M3U Playlist files for use in Winamp or most FrontEnds. In addition, it copies the actual music files over to any desired folder on the CarPC. This ensures that the correct folder structure is maintained and that the playlist can correctly link to the files.
Requirements:
1) iTunes must be organized
For iTunes, you must set iTunes to “Keep iTunes Music folder organized” and “Copy files to iTunes Music folder when adding to library” (Edit -> Preferences -> Advanced). To make sure that all of the source files are in the right place, you will probably want to “Consolidate Library” as well (Advanced -> Consolidate Library) before trying to convert a playlist.
If Transfer across network.
2) You must be networked
You must have your Desktop PC and your CarPC connected over a network at least temporarily during the transfer. The desired destination for the music on the CarPC must be shared in Windows at all times, even after the transfer is completed. A snafu to this is, once its copied, run the program and for destination folder type in the directory as it is on remote PC (Windows File Sharing Bug, avoidance)
The reason for initially making this was my carPC does not have enough HD space to hold all my music, so pick what songs i want and creating a playlist for them would be very inefficient, so i created a program that will accomplish that.
A brief how-to of the program: create play list, export it as appropriate file type. run program select the exported playlist, where you want to to convert the playlist to and whether you want to copy the files there.
[EDIT]
Okay folks, i am going to release the source code. So people can take a look and figure out how it works and trouble shoot any issues.
