We are confident you will find it useful and extremely easy to use. Many computer users find it necessary to share data between different computers but in this world of multiple computer types, there usually ends up being more than one format for storing data on a disk. These formats usually differ in the way directories and files are accessed. Sometimes they also differ in the way the actual data bits are stored on the disk. Both instances are the case with MS-DOS/PC-DOS and Atari ST formatted disks and standard Amiga formatted disks. CrossDoS is a software product that allows the user to read and write MS-DOS/PC-DOS and Atari ST formatted disks (Version 2.0 or higher) directly from AmigaDOS. It fully integrates itself into the Amiga operating system to allow your MS-DOS formatted disks to be accessed from virtually any utility or application, jast as any other Amiga file. NOTE All further references to MS-DOS formatted disks also apply to PC-DOS and Atari ST formatted disks unless otherwise specified. Imagine working on a spreadsheet file on your PC and continuing to work on it using your Amiga spreadsheet application (such as Analyze!, Plan/It or others). Or you can transfer a WordPerfect document created on your Amiga and read it into your PC version of WordPerfect. Ypu can create a picture with DeluxePaint on the PC and view it on your Amiga using the Amiga version of DeluxePaint. Many other data sharing can be done between databases, language compilers, CAD programs, etc. A properly mounted MS-DOS device will allow you to access any file on an MS-DOS formatted disk as if it were any other valid AmigaDOS disk. You can then proceed to access an MS-DOS disk from any application. CrossDOS ... The MS-DOS File System 1.1 Feature Summary A summary of the main features of CrossDOS are: - MS-DOS formatted disks are integrated as part of the Amiga operating system allowing access from virtually any Amiga utility or application (including file requesters). Perform most AmigaDOS functions: - Read and write any file. - Relabel the disk name. - Create directories. - Rename any files or directories within or across directories. - Set file or directory dates and protection bits. - MS-DOS formatted disks (Versions 2.0 and higher) are supported. - standard density, 80 track, 3 1/2" floppies (720 K) - standard density, 80 track, 5 1/4" floppies (720 K) - standard density, 80 track, 5 1/4" floppies used in double track step mode (360 K) - standard density, 40 track, 5 1/4" floppies (360 K) Two ASCII text filter options are provided. Disk changes are sensed automatically (if the drive provides the proper hardware signal). Floppy disk parameters are sensed automatically (ie. double-sided, single-sided, 8 or 9 sectors/track, etc.). ".infoV file extensions are supported for use with WORKBENCH. Double Track Step Mode is available to read and write standard 40 track floppies on an 80 track, 5 1/4" drive. Minimal memory is required (approx. 80 bytes) when the file system is not accessed. "Kill" utility can be used to recover resources and memory after use. Special utilities to format, diskcopy and check the integrity of MS-DOS disks are provided. Software is not copy-protected. 1.2 Hardware Requirements CrossDOS requires a standard Amiga (500, 1000, 2000, 2000HD or 2500) with at least 256K bytes of memory. This product includes a special device driver, "mfm.device", for use with the standard Amiga 3 1/2" and 5 1,/4" floppy drives. .
