UPX是一个通用可执行文件压缩器，由于其具有：
压缩率高：压缩效果优于zip/gzip；
解压速度快：在奔腾133上即可达到大约10MB/秒；
压缩的可执行文件没有额外的内存开销；
安全：可以列表，检测和解压可执行文件，压缩和解压缩文件内部都维持有一个校验和；
广域：可以压缩多种可执行文件格式：
dos/exe
dos/sys
dos/com
djgpp2/coff
watcom/le ( 支持DOS4G, PMODE/W, DOS32a 和 CauseWay )
win32/pe
rtm32/pe
tmt/adam
linux/386
atari/tos
免费
等特性，因此其也成为我们在压缩可执行文件时的首选工具。
UPX是一个控制台应用程序，以命令行方式进行操作，其使用是极其简单的：
upx [-命令] [-选项] [-o 目标文件] 源文件..下面我们以UPX 1.07W为例，具体讲解其使用方法。默认情况下，UPX将直接对源文件进行操作，但也可指定目标文件，而不覆盖源文件，文件名支持通配符，即一次可对多个文件进行同一操作。
一、显示 UPX 通用信息（版权信息，使用说明等），在命令行直接输入 UPX 并回车。
