Remove missing tracks in iTunes

As I wanted to remove missing files in iTunes automatically , I tried to find a way to make it.
Eventually, iTunes COM for Windows SDK License Agreement was the one that I have been looking for.

The following is the way that I took.

1. Download "iTunesCOMWindowsSDK.zip" from the site above.
2. Unzip the file above. The folder "iTunesCOMWindowsSDK" would be created.
3. Move the folder "iTunesCOMWindowsSDK" to C drive.
4. Open the Run dialog box with WindowsKey + R.
5. Input the command as follows.
wscript C:\iTunesCOMWindowsSDK\iTunesCOMWindowsSDK\SampleScripts\RemoveDeadTracks.js

Basically that's it. The script starts to remove missing tracks in iTunes silently. When it finish its process, you can see the following message or something like that.



I am wondering why this functionality is not implemented in iTunes itself, though...
