I have 11 tourney's in H2N and can only see the last hand history and all history in game folder is gone/deleted
You can also find all the processed hand histories in the archive folders. By default, the archive folder is C:\MyHandsArchive_H2N, but the path can also be changed in auto-import settings. Hand histories from Chinese apps and other rooms that don't require auto-import settings are stored in C:\Hand2NoteHH.
You can disable archiving hand history in Configuration -> Autoimport, but it's not recommended. H2N scans the folders during autoimport, so the more files are there - the longer it takes and the worse overall performance will be. Autoimport folders must be empty for optimal H2N operation
