Features of Commodore DOS
Actions such as formatting floppy disks, renaming, deleting or copying files are therefore carried out by Commodore DOS and take place entirely in the drive unit. DOS offers a flat file system (see SFD100x for details) without subdirectories and with a limited number of entries, i.e. files, per data medium (floppy disk or hard disk). The maximum number of entries varies with the capacity of the respective data medium, from 170 KB diskette to 4.5 MB hard disk drive.
