path.data

path.data is fairly simple. It contains a mapping of ID's to asset paths.
The file starts with 4 bytes representing a 
timestamp in unix epoch and 4 bytes representing the total number of paths in the file.
Each path consists of a varying number of bytes. The first 4 bytes of a path are the ID, the next 4 bytes are the length of the path in bytes. Reading bytes equivalent to the length will give you a 
GB2312 encoded string representing the path.

path.data export.

An example C# class representing the data.
public class PathData
{
	public Int32 Timestamp { get; set; }
	public Int32 TotalPaths { get; set; }
	public ESOPath[] ESOPaths { get; set; }
}
public class ESOPath : PathData
{
	public Int32 ID { get; set; }
	public Int32 PathLength {get; set;}
	public String? FilePath { get; set; }
