HDCopy
HDCopy is a disk image application for floppy disks that runs in MS-DOS. It can copy a floppy on the fly, or by using archives with IMG file extension that store the content of the disk with a proprietary file format (whose first three bytes noted in hexadecimal will be FF 18, and its size will be anything). For the proprietary file format compression can be used or deactivated. The compression algorithm is called "Byte-Run-2-Algorithm" by the author.hd-copy.dok - Manual shipped with HD-Copy It was written by Oliver Fromme and is distributed as cardware. Do not confuse the ''HD'' in its name with ''hard disk''. HD represents ''high density'' (floppy disks with capacity greater than 1.2 MB). In the early 90s, when floppy diskettes for PCs were widely used, HDCopy was extremely popular in many places. Its usage started to decline as floppy disks became less widely used.

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardware
Shareware is a type of proprietary software that is initially shared by the owner for trial use at little or no cost. Often the software has limited functionality or incomplete documentation until the user sends payment to the software developer. Shareware is often offered as a download from a website or on a compact disc included with a magazine. Shareware differs from freeware, which is fully-featured software distributed at no cost to the user but without source code being made available; and free software, free and open-source software, in which the source code is freely available for anyone to inspect and alter. There are many types of shareware and, while they may not require an initial up-front payment, many are intended to generate revenue in one way or another. Some limit use to personal non-commercial software, commercial purposes only, with purchase of a license required for use in a business enterprise. The software itself may be time-limited, or it may remind the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
