In Windows and Dos it will copy a file from your hard disk to your disk drive, in the case that the file Taille is bigger than the Taille available in your disk drive. Once copied it is possible to restore the disk(ette)s to another computer. You can copy any big file via ordinary diskettes! This small tool can be very usefull on your Système disk to safeguard important big files in case Windows is not working or crashed caused by virus attack for instance.
Also splitting and rejoining of a file into a number of pieces directly in a directory is possible (eg. to split E-mail attachments).

Dos based Utilitaire for Windows users. Seems strange but is very handy for the case when Windows crashes... which sometimes happens.
