How many of these have you got?
Is the name of the textfile always the same?
I don't think there is a way of doing this with Media Center as it stands.
Someone correct me if I'm wrong.
However I've written a utility called the C# Script Plugin.
It allows scripts to be run which allow a lot of flexability on things like this.
Scripts are little snippets of code that can be run on the fly while Media Centers running.
I've written a script which I think could do what you want.
If you want to try it you will have to install the C# Script Plugin available
here.You won't need to do any coding, as long as you can copy and paste your ok!
Just copy the script from
here (Everything below the word
Script:) and paste into a new script within the plugin.
(Hit the new script button, a sample script is generated, replace that with the one above)
The script currently looks for a text file called ExtraInfo.txt.
Instructions are provided with the script to change this to what ever your text file
is called in your album directory.
The script currently places the information retrieved in the Comment field.
When your ready to run the script just press run script button.
The script is applied to all tracks in the playing now list.
If you decide to try this, and run into any difficultys just let me know!
Run it on a few sample tracks to confirm the desired effect before trying it on your entire collection.
