Hi Jan
Thanks for that. Think I have found a way round myself.
First problem is this.
iTunes recommend setting up a playlist for the songs you wish to convert. However, if you do this, when the conversion is done it puts the converted file back in the main library, not in the playlist, so you can't see it.
After having tried to convert a number of times, I went back to the main library to find several versions there.
Anyway, still doesn't help in moving the files.
So from there I use the main computer search function to locate the file I want. I find you only need the first word of the title to locate all the files. From there, if you hit 'see more results' it will list all the files with their respective formats next to them.
From there its 'drag and drop' to the specific folder.
Sounds complicated, but simple once you get into the rhythm.
I went through my iTunes library and found 129 songs to convert.
Once I had figured it out, spent a happy evening putting them all on flash drive.
No doubt there are more sophisticated ways, but this worked for me.
