- You can test this setup is working correctly by hashing the contents of {{ :test_dir_structure.zip |this zip}} and comparing the datfile that clrmamepro creates with {{ :test_dir_structure.dat.zip |this pre-made datfile}} . Currently there is no solid solution for "directory hashing" that supports SHA256, so you can leave that hash type out.

+In the created datfile, directories, including empty ones, are represented as files with a size of "0" and a CRC32 of "-", and no other attributes. The filename is set as you would expect (e.g. "dirwithemptydir\emptydir2" for one of the directories in the example, except it will have "_" appended to it when clrmamepro is used on Windows, and "\_" when clrmamepro is used on Linux with Wine. There will also be an archive called "Default" with a single empty folder, which should be ignored/deleted.
