Deleting library

Is there a way to delete My library? Afterski updating to build 29 sametinget happened. Roon couldnt fond any music on My NAS. So I importen everything. Bit now I have up to 5! Duplikatens of all albums. Instegade of manuellt deletin afterski album I thought I light deleting the whole library and import again. Thoughts?

Exit Roon, then

On a mac: delete /Users/YOUR_USERNAME/Library/Roon/Database
On windows: delete c:\Users\YOUR_USERNAME\AppData\Local\Roon\Database

Then restart Roon. It will ask you to log in again and stuff, but you should be basically starting fresh as far as the library goes.
