It also says there that multithreaded applications should not use relative paths. It seems that WinAPI functions which allow relative paths suffer from the same problem: They have to call GetCurrentDirectory too and are therefore not thread-safe either. That means that you can use relative paths only for single-threaded programs. Then it would not matter whether GetCurrentDirectory is called from FPC (while expanding) or through the WinAPI. So I see no harm in predending '\\?\' and expand relative paths if needed. Programmers who do not think/know about the special handling of long paths under Windows (maybe because they started with Linux) would still get a program that works with long paths too. I think this is expecially important because of the multi platform approach which IMO means that the programmer should *not* need to think about OS specialities (as far as possible). There are enough of them left which the programmer has to take care about, no need to add those who are avoidable. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
