I suspect you are probably right about the child_folder note - although you have to watch that links stay the web way, and only Windows paths go the Windows way. 

Hmm - the split may need to be translating one OS separator to the other - although I am not sure about the legality of forward slashes in unix file names or backslashes in windows file names. I may be in danger here of assuming that they are not legal in them - and besides - if shared via source control, dropbox or some other means between them - it would be a problem there too - so this should be a safe assumption.
