首发原帖：FFSJ: The Fastest File Splitter and Joiner v3.3 号称最快的文件分割、合并工具 @ ACQBBS
现在文件越来越大的，尤其是音、视频文件，常常需要将文件分成多个比较小的文件通过网盘等进行分享。使用压缩软件，速度比较慢；最简单高效的方法就是将文件分割。FFSJ 这个软件就是实现这个功能，号称比其他相同功能的软件 HJ-Split, WinSplit, MasterSplitter 快3到5倍。
- 分割：可以指定分割的块数（即指定分割成几部分），也可以指定分割后每部分文件大小
- 合并：支持在不同路径下的分割后文件合并成一个文件
FFSJ is...
Very fast: FFSJ can optimize disk-cache and memory usage, this makes FFSJ 3-5 times faster than HJ-Split, WinSplit, MasterSplitter in both splitting and joining tasks. Of course, it is much faster than any compression program.
Simple: FFSJ works well on all Windows platforms. FFSJ-Lite doesn't need any requirement of installations or complicated DLLs. FFSJ-Standard has only one simple installation package for integrating FFSJ into shell context menu.
FFSJ 能在所有 windows 平台下使用，分为两个版本：FFSJ-Lite 是单个文件，直接运行就可以使用；FFSJ-Standard 是个安装包，除了包含 FFSJ-Lite 外，还在资源管理器增加了右键菜单，方便使用。
Small: Both FFSJ-Lite and FFSJ-Standard editions are small enough to fit on a floppy disk.
Easy to use: FFSJ has a friendly user-interface, it can be used to split any file. FFSJ-standard can also create its shell context menus in order to perform splitting and joining tasks directly from Windows Explorer.
Easy to be integrated: Since v3.0, FFSJ published its command-line interface. End-users can split/join multiple files using a .BAT file. Developers can write their own interface (in any language) to perform splitting/joining tasks from their applications.
FFSJ 支持命令行模式，可以使用在批处理文件中。Secure: FFSJ uses an advanced encryption algorithm to make your data much more secure from unauthorized access. Since v2.9, MD5 checksum algorithm has also been integrated to verify data integrity.
