Ok, so this post is really not about development (i.e. this is a developer blog), but I just needed to get this weirdness off my chest.
Recently I had the need to move my iTunes library - all the physical files that is - to a new location on my Windows system. Now, I don't use iTunes Media folder due to the "Keep iTunes Media folder organized" setting, since I don't want iTunes to try and organize my music files. I like to handle that myself. However, all guides I could find about moving the iTunes library made use of the Media folder, so I wanted to find another way. The problem is, though, that in theory there isn't any other way.
With iTunes shut down I started to look into where it stores its library information. In Windows that is somewhere like this: C:\Users\[username]
In this folder there is a file called "iTunes Library.itl". The file contains information about all music files, including the full path of each music file. But the library file is in a proprietary format with no easy way of reading. Next to the .itl file is another library file called "iTunes Music Library.xml". This XML file contains the same information about the music files, and since it is XML it can be read into any text editor.
So I tried to do a search and replace to change the paths pointing to the music files to the new location. I saved the file and fired up iTunes. But it just ignored the XML completely and started up with an empty library. I then went through all the menus in iTunes to see if I could find a way to do an import of the XML file. No such luck. So I did some more research on the Internet and finally found a post, which after reading I really had my doubts about. But since I couldn't find any other suggestions, I decided to give it a shot.
The procedure is this:
- Close iTunes.
- Open the XML library file in a text editor and fix all file paths to point to the new location, and then save file.
- Open the .itl file in a text editor (it will look all weird) and just remove some of the contents, and then save file. This causes the file to be damaged, which is the intention.
- Start up iTunes. It should now notify you that it is reading the XML file, and after a while iTunes will open up with the relocated library loaded.
Ok, so I just found out something about the XML library file. It is possible to generate it by exporting the library from within iTunes. It's just that finding the correct menu item for this can be a bit tricky. Nowadays, the default setting for the menu bar in iTunes is to not show it. There is, however, a menu at the top left corner in which there is a Library submenu. The problem is, though, that this does not contain anything for exporting the library. Instead you have to select Show Menu Bar, which shows the full menu bar. Then go to File->Library, and this Library submenu does contain a Export Library menu item, which you can use to export the library to XML.
I guess I didn't get the memo when they made that design decision :)
