Well, this is as huge an ouch as they likely make them. The only practical way out of this I see is to restrict the file names you let windows handle to the subset they handle consistently, the rest of the effort will be a (potentially huge) waste of time & effort. Even if you somehow manage to cover for all cases your solution will work only until their next version or even revision. > ... >>> E.g., Makefile and makefile collide in Windows' namespace.

Uhm, relying on a character case you type in to have a different file name is nothing I would cann otherwise :-). I can easily see how a programmer can be tempted to do so in a quick hack but it is similar to patching object code in hex without changing the source code "just this once to see what happens". Things like that are bound to bite back, who of us has not been bitten. (Actually I still do patch code sometimes like that but rarely and I must have become better at being cautious enough not to get bitten... or used to the bites and not even noticing them :D ). > Again, recall that I'm using these as "object names", not FILE names. I get that, so you are absolutely fine with say 64 bits per object ID (strictly it is not a "name", names are written in text and text at its basic level is case independent). But you just cannot feed binary data into something expecting text as an input and hope things would work, you will have to put a translation layer between the two. I just don't see any way around it. Say a file in your directory mapping all your 64 bit entries into text names or something.
