# Just a normal copy program, BUT it never overwrites a file in the destination.
# if the filename is already taken, the new file will get an incrementing number as postfix added just in fron of the dot before the extension.
# no extension, its added the end.
# example: filename.wav already exists, new file will get the name filename_1.wav.
