Hi Andrew,
The 49-Paks often include RT/RDs that are not shipped with the core product and I have bought all of those over the past decade or more. I am also pretty sure that some of the Xtrastyles/Xprostyles sets (and I have bought all of these) included some additional (non-core) RT/RDs.

This is why PG advised me to copy the new RT/RDs from each new version over the top of my existing RT/RD folders (rather that deleting the existing folder contents before copying the new version over) so that I wouldn't lose these 'non-core' RT/RDs.

For this reason, the feature you mention to delete unwanted (I take it you mean 'duplicate'?) Wav/WMA files would be really useful sooner rather than later.

Many thanks

Regards, Aubrey
