If you want to run a non-Windows executable on Windows, you need to use an alternate shell - someone mentioned Cygwin - although I'm not certain that even that will do it for you. What makes an executable OS-specific is not the language it's written in, but the libraries that it's compiled/linked with. If you have access to the source code, the simplest thing would probably be to recompile it on your own machine... the GCC (Gnu Compiler Collection) is free. You mentioned the 'A' attribute - in Windows, that stands for Archive, and was created as a way for early backup programs to do differential backups (i.e. you do a full backup - the backup program copies every file, clearing the A attribute as it does so; new and updated files have the A attribute set, so the next time you do a backup, the program only copies files that have the A attribute...) -- www.fsrtechnologies.com
