I've been trying to copy files off a Windows XP shared folder in Windows explorer, and it keeps telling me that I don't have permission to do so. When I look at the files permissions with ATTRIB, I see that it is read-only, and when I look at the file with DIR /Q, I see that its owner is PENGUIN\dave. That's the username under which I've mounted the drive. So then it occurs to me, maybe Cygwin permissions are getting in the way somehow. I do a chmod -R g+r on the directory and presto, I can copy files! What confuses me about this is that: a. I'm connected as the owner of the file, so why should group permissions make any difference? b. Windows XP doesn't seem to have the notion of group permissions. I can find "Groups" if I dig hard, in Administrative Tools> Computer Management, but I don't see any indication that I can set or view group permissions. On the other hand, what are Groups for if not controlling access? So, can anyone explain this? Also, is there a comprehensive overview of the relationship between the Cygwin and Windows filesystems somewhere?
