FileAndDirs: Dealing with Files and Directories

Overview
With version 15.0 Dyalog has introduced several new system functions that make it much easier to write platform independent code when it comes to dealing with files and directories.
However, there are some gaps left: copying and moving files for example, or a recursive directory listing.
FilesAndDirs aims to close this gap: it offers the same functionality for Windows, Linux and Mac OS.
Slashes and backslashes
Under Windows the backslash \ character is used as delimiter. Under Linux and Mac OS it is the / character. However, Windows is willing to accept the / rather than the \ in most cases, and in all when we do something by a program. The easiest way therefore seems to be to use / everywhere.
Yes and no. A backslash character is under Linux potentially a legal character in a filename or a directory name. That can cause problems of course if you specify a \ character under Linux by accident.
FilesAndDirs normalizes all filenames and all directory names for you, so you cannot forget this. That's the reason why the class offers method like Exists, CreateFile and DeleteFile: they don't do much more than their system function equivalents, accept that they normalize any filenames and directory names.
Of course this means that FilesAndDirs cannot deal under Linux and Mac OS with names that contain a \, but if you try to write platform independent code then you should not do this anyway.
