AllFilesMask
When searching for all files in a folder, it helps to know if the operating system treats ALL files as '*' or '*.*', so we have included a constant that is set by the operating system at run-time. When doing a FindFirst(...) for example, you can pass path + AllFilesMask and know that you are looking for all files in the folder for the current operating system.These features are included so you will code your application to work on multiple platforms without error.
