Hi Frank Attached is a patch for filename.pas to cater for MSYS. Since MSYS is a fork of the Cygwin project, many things that apply to Cygwin apply to MSYS as well. You can ignore my previous post about front slashes, FileExists, et. al. This patch fixes all those issues. Thanks. Best regards, The Chief -------- Prof. Abimbola A.
