This hasn't got to do with Reason. Some (3rd party) sample folders got deleted so Reason just informs me that the samples cannot be found anymore.
However, if I'm left with only the file names of the missing samples, but not the name of the sample pack that they are from, then how can I discover which sample packs do I need to redownload?
