	/// <remarks>
	/// The following features are missing from DATabaseTwo with respect to the original DATabase:
	/// - Source merging
	/// - Custom DATs based on a system and a source
	/// - Multi-source and multi-system DATs
	/// 
	/// The following features need to (want to) be implemented in DATabaseTwo for further stability
	/// - Import updating file locations and names when SHA-1 hashes are matched
	/// - True duplicate DATs being removed from the import folder (SHA-1 matches)
	/// - Generate All only generating DATs that have been recently updated
	///		+ This requires implementing a "last updated" data point for all DATs and tracking for "last generate" somewhere
	/// - Impelement a ToSort folder for DATs that will place DATs in the correct subfolder on Import
	/// </remarks>
