Very simply, I'm requesting a link to download all the various dat infos in one zip, arranged in a sensible hierarchy:
(Small selected sample)
Fujitsu FM Towns series\cues Fujitsu FM Towns series\dat\ IBM PC compatible\cues\ IBM PC compatible\dat\ IBM PC compatible\sbi\ IBM PC compatible\led\
Alternatively, possibly the better option, is include a single folder for each disc type with all relevant files in that folder and just negate the need for subfolders per file type. This is probably the preferred option for both the user and for you as a coder.
