How to restore learnt settings manually?

I had a disk crash and have reloaded the app.

I have a copy of my old SpamSieve application support library which includes:

Corpus.corpus (folder)
|-- info.plist
|–MessageIDs
|–Words201

False Negatives (Folder)
|-- $#@%!@# ==.eml (files lots of them with gobble-gook prefix)

I want to retain the training and info. What files do I copy across to new SpamSieve app Support folder to do this?

It’s safest to restore everything in the Application Support folder. That way you would get what you need even if a new version of SpamSieve adds more files. However, currently the only files that have training data are “Corpus.corpus” and “Rules”. You might also want the accuracy statistics in “History.db”.
