下载了CoH2_RGDTools_v1.2a，解压出来有很多文件，然后怎么样把rgd文件转格式？

2. Usage rgdConv:
rgdConv converts between CoH2-RGDs and a text-based format (or XML).
Usage: rgdConv.exe <hashdict> <inputdir> <outputdir> [-x|-j] [-r|-t]
-x convert to/from XML instead of text
-j convert RGDs to JSON (no JSON to RGD available)
-r convert RGDs to text (/XML)
-t convert text (/XML) to RGD
If none of the above is specified, both conversions will be applied
If it encounters any unknown hash values during the conversion, it will create a file called 'unknown_hashes.txt' listing them.
