【WinRAR是哪个国家的品牌？】

知名软件品牌，软件运营服务商，可以备份数据，减少E-mail附件的大小，界面友好的压缩文件管理工具。

WinRAR 是一个强大的压缩文件管理工具。它能备份你的数据，减少你的 E-mail 附件的大小，解压缩从 Internet 上下载的 RAR、ZIP 和其他格式的压缩文件，并能创建 RAR 和 ZIP 格式的压缩文件。在购买之前，你可以下载试用版本。

WinRAR是一个文件压缩管理共享软件，由Eugene Roshal（所以RAR的全名是：Roshal ARchive）开发。Pocket RAR是为Pocket PC平台发布的免费软件。它是仅有的几个可以读写RAR文件的软件之一，因为它保留版权。

WinRAR 是目前流行的压缩工具，界面友好，使用方便，在压缩率和速度方面都有很好的表现。其压缩率比高，3.x  采用了更专业的压缩算法,是现在压缩率较大、压缩速度较快的格式之一。 3.3 增加了扫描压缩 文件内病毒、解压缩“增强压缩” ZIP 压缩文件的功能， 升级了分卷压缩的功能等。

WinRAR 在 DOS 时代就一直具备这种优势，经过多次试验证明，WinRAR 的 RAR 格式一般要比其他的 ZIP 格式高出 10%～30% 的压缩率，尤其是它还提供了可选择的、针对多媒体数据的压缩算法。

WinRAR 对 WAV、BMP 声音及图像文件可以用独特的多媒体压缩算法大大提高压缩率，虽然我们可以将 WAV、BMP 文件转为 MP3、JPG 等格式节省存储空间，但不要忘记 WinRAR 的压缩可是标准的无损压缩。

虽然其他软件也能支持 ARJ、LHA 等格式，但却需要外挂对应软件的 DOS 版本，实在是功能有限。但 WinRAR 就不同了，不但能解压多数压缩格式，且不需外挂程序支持就可直接建立 ZIP 格式的压缩文件，所以我们不必担心离开了其他软件如何处理 ZIP 格式的问题。

我们知道不能建立多卷自解包是某种压缩软件的的一大缺陷，而WinRAR处理这种工作却是游刃有余，而且对自解包文件还可加上密码加以保护。

英文翻译：Well known software brands, software operators and service providers, can backup data, reduce the size of e-mail attachments, interface friendly compressed file management tools. WinRAR is a powerful compressed file management tool. It can back up your data, reduce the size of your e-mail attachments, decompress the RAR, zip and other compressed files downloaded from the Internet, and create the RAR and zip compressed files. Before you buy, you can download the trial version. WinRAR is a file compression management and sharing software developed by Eugene roshal (so the full name of RAR is roshalarchive). Pocketrar is a free software released for the PocketPC platform. It is one of the few software that can read and write rar files because it retains the copyright. WinRAR is a popular compression tool with friendly interface and convenient use. It has a good performance in compression rate and speed. Its compression ratio is high. 3. X uses a more professional compression algorithm, which is one of the formats with larger compression ratio and faster compression speed. 3.3 added the functions of scanning the virus in the compressed file, decompressing the "enhanced compression" zip compressed file, and upgrading the function of volume splitting compression. WinRAR has always had this advantage in the era of DOS. It has been proved by many experiments that WinRAR's rar format is generally 10% - 30% higher than other zip formats in compression rate, especially it also provides optional compression algorithm for multimedia data. WinRAR can greatly improve the compression rate of WAV, BMP sound and image files with unique multimedia compression algorithm. Although we can convert wav, BMP files to MP3, JPG and other formats to save storage space, don't forget that WinRAR compression is standard lossless compression. Although other software can also support ARJ, LHA and other formats, it needs to plug in the DOS version of the corresponding software, which has limited functions. But WinRAR is different. It can not only decompress most compressed formats, but also directly create zip compressed files without the support of plug-in program. So we don't need to worry about how to deal with ZIP format without other software. We know that it's a big defect of some compression software that we can't build multi volume self unpacking, but WinRAR can handle this kind of work easily, and we can protect the self unpacking file with password.
