DOS时代有一些很好的工具软件，也有一些经典的小游戏，其博弈智能水平决不输于现在的许多3D大制作游戏。由于DOS时代人们多用软盘作为贮存介质进行交流，所以这些程序即使是存放在光盘上，也和今天我们熟悉的存放方式有些区别，要利用DOS宝库，应该使用下面这5个工具程序：
HD-COPY.EXE软盘复制、格式化以及IMG影像文件制作与还原。
IMG.EXE最方便的影像文件还原软件。
ARJ.EXE文件压缩与解压。
PKUNZIP.EXE zip文件解压。
RESTORE.COM备份文件还原。
HD-COPY的用法上文已有叙述。IMG.EXE是针对HD-COPY和另一个叫DDUP的拷贝软件而编制的。HD-COPY能将软盘完整地制作成.IMG影像文件保存，但在使用时，还必须再次用HD-COPY将.IMG影像文件转存到软盘上。有了IMG.EXE，就省去了这一麻烦。IMG.EXE在内存中直接开出一张软盘容量大小的区域，模拟软盘，并将.IMG影像文件还原到这个模拟软盘中，然后用户可以将模拟软盘上软件安装到硬盘。并且IMG.EXE使用“Ctrl+Alt,S,D,X”这一个热键来进行切换，所以可以连续处理多张软盘。使用“Ctrl+Enter”可以将IMG.EXE从内存中清除。如果你看到DOS时代的文件是以.IMG或.DDI为扩展名，那么这多半是软盘影像文件，就可以使用IMG.EXE来完成安装。
如果DOS文件是以.ARJ、.001、.002、……为扩展名，那么这是用ARJ.EXE制作的压缩文件，再用它解压就行，可以通过DOS命令“ARJ /?”来调出使用帮助。
同样可以用PKUNZIP.EXE来还原以.ZIP为扩展名的压缩文件。
RESTORE.COM用来还原用BACKUP备份的文件，BACKUP命令各个DOS版本之间不直接兼容，但可以指定版本，现在我们没有必要了解这些了，注意使用一个较高的DOS版本和RESTORE.COM就行，它向下兼容。
Essential Tools for DOS Software

There were some very good tool software and some classic small games in the DOS era. The gaming intelligence level of these games is by no means inferior to many current 3D big-production games. Since people in the DOS era mostly used floppy disks as storage media for communication, these programs, even if stored on CDs, are somewhat different from the familiar storage methods today. To access the DOS treasure trove, you should use the following 5 tool programs:
HD-COPY.EXE for floppy disk copying, formatting, and IMG image file creation and restoration.
IMG.EXE the most convenient image file restoration software.
ARJ.EXE for file compression and decompression.
PKUNZIP.EXE for zip file decompression.
RESTORE.COM for restoring backed-up files.
The usage of HD-COPY has been described above. IMG.EXE is compiled for HD-COPY and another copying software called DDUP. HD-COPY can completely create an.IMG image file of a floppy disk for storage, but when using it, you must again use HD-COPY to transfer the.IMG image file to a floppy disk. With IMG.EXE, this trouble is omitted. IMG.EXE directly opens an area of the size of a floppy disk capacity in memory, simulates a floppy disk, and restores the.IMG image file to this simulated floppy disk, and then the user can install the software on the simulated floppy disk to the hard disk. And IMG.EXE uses the hotkey "Ctrl+Alt,S,D,X" for switching, so multiple floppy disks can be processed continuously. Using "Ctrl+Enter" can clear IMG.EXE from memory. If you see a file from the DOS era with the extension.IMG or.DDI, then this is mostly a floppy disk image file, and IMG.EXE can be used to complete the installation.
If a DOS file has the extension.ARJ,.001,.002, etc., then this is a compressed file created with ARJ.EXE, and it can be decompressed with it. You can call up the usage help through the DOS command "ARJ /?".
Similarly, PKUNZIP.EXE can be used to restore compressed files with the.ZIP extension.
RESTORE.COM is used to restore files backed up with BACKUP. The BACKUP command is not directly compatible between different DOS versions, but a version can be specified. Now we don't need to understand these. Just note that using a higher DOS version and RESTORE.COM is fine, and it is backward compatible.
