解压软件也叫压缩软件，可以把压缩文件里的文件给解压出来，也可以把文件压缩可以缩小文件的体积，减小硬盘的占用。软件是根据16进制数字重叠原理来制定压缩算法来压缩文件。常见压缩解压软件有：WinRAR、360压缩、好压。 解压软件也叫压缩软件，可以把压缩文件里的文件给解压出来，也可以把文件压缩可以缩小文件的体积，减小硬盘的占用。压缩软件和解压缩软件是根据 16 进制数字重叠原理来制定压缩算法来压缩文件，目前只能对 32 位和 16 位文件进行压缩，64 压缩算法尚不成熟。
Decompression software is also called compression software. It can extract the files in the compressed files, or compress the files to reduce the volume of the files and the occupation of the hard disk. Software is based on the principle of hexadecimal digital overlap to develop a compression algorithm to compress files. Common compression and decompression software: WinRAR, 360 compression, good compression. Decompression software is also called compression software. It can extract the files in the compressed files, or compress the files to reduce the volume of the files and the occupation of the hard disk. Compression software and decompression software are based on the principle of hexadecimal digital overlap to develop compression algorithm to compress files. At present, only 32-bit and 16 bit files can be compressed, 64 compression algorithm is not mature.
常用的有 WinRAR、7-ZIP、WinZip 和好压（HaoZip），其中 7-Zip 和好压是免费的，特别的，好压是国人发明的新一代压缩软件。
Commonly used are WinRAR, 7-Zip, winzip and HaoZip, of which 7-Zip and HaoZip are free. Especially, HaoZip is a new generation of compression software invented by Chinese people.
At present, WinRAR is a popular and easy-to-use compression and decompression tool, which supports mouse drag and drop and shell extension, and perfectly supports zip files. The built-in program can unlock cab, ARJ, lzh, tar, GZ, ACE, uue, bz2, jar, ISO and other types of compressed files. It has estimated compression function, so you can use zip and RAR before compressing files The approximate compression ratio of the two compression tools in each of the three compression modes; with the function of historical record and favorite; the compression ratio is quite high, while the resource consumption is relatively small.
在安装完毕后，WinRAR 的功能会自动添加到鼠标右键的快捷菜单中，将下载的 RAR 格式文件移动到一新建的文件夹中，选中，点右键，选择“解压到当前文件夹”即可。要建立压缩文件，只要选中文件，点右键，选择“添加到压缩文件”即可。
After installation, WinRAR’s functions will be automatically added to the shortcut menu of the right mouse button. Move the downloaded rar format file to a new folder, select it, right-click, and select “extract to current folder”. To create a compressed file, just select the file, right-click, and select Add to compressed file.
其他软件的使用方法与 WinRAR 大同小异。
The use of other software is similar to WinRAR.
