Files can be copied with the same name or with a new name. /Y - Causes COPY to replace existing files without providing a confirmation prompt. By default, if you specify an existing file as the destination file, COPY will provide a confirmation prompt. (In previous versions of DOS, existing files were simply overwritten.) /-Y - Displays a confirmation prompt before copying over existing files. /A - Used to copy ASCII files. Applies to the filename preceding it and to all following filenames. Files will be copied until an end-of-file mark is encountered in the file being copied. If an end-of-file mark is encountered in the file, the rest of the file is not copied. DOS will append an end-of-file mark at the end of the copied file. /B - Used to copy binary files. Applies to the filename preceding it and to all following filenames. Copied files will be read by size (according to the number of bytes indicated in the file`s directory listing). An end-of-file mark is not placed at the end of the copied file. /V - Checks after the copy to assure that a file was copied correctly. If the copy cannot be verified, the program will display an error message. Using this option will result in a slower copying process. &nbsp; &nbsp; == [[Category:Computer_Technology]] [[Category:Microsoft]] [[Category:Windows]] [[Category:DOS]] [[Category:MSDOS]]
