What is diskcopy.dll?

Part of Windows DiskCopy by Microsoft

What is it?

Copies the contents of the floppy disk in the source drive to a formatted or unformatted floppy disk in the destination drive. Used without parameters, diskcopy uses the current drive for the source disk and the destination disk.
Description of diskcopy.dll from Microsoft
Because diskcopy makes an exact copy of the source disk on the destination disk, any fragmentation on the source disk is transferred to the destination disk. Fragmentation is the presence of small areas of unused disk space between existing files on a disk. A fragmented source disk can slow down the process of finding, reading, or writing files. To avoid transferring fragmentation from one disk to another, use copy or xcopy to copy your disk. Because copy and xcopy copy files sequentially, the new disk is not fragmented.
(diskcopy.dll is a system file that is installed with Windows)
