Shanghai Softlight Information Technology Co., Ltd., WinRAR, a well-known software brand and software operation service provider, can back up data, reduce the size of E-mail attachments, and compress file management tools with a friendly interface
WinRAR is a powerful compressed file management tool. It backs up your data, reduces the size of your e-mail attachments, decompresses compressed files in RAR, ZIP and other formats downloaded from the Internet, and creates compressed files in RAR and ZIP formats. You can download the trial version before purchasing.
WinRAR is a file compression management shareware developed by Eugene Roshal (so the full name of RAR is: Roshal ARchive). The first public version, RAR 1.3, was released in 1993. Pocket RAR is a free software released for the Pocket PC platform. It is one of the few software that can read and write RAR files as it retains copyright.
WinRAR is a popular compression tool at present, with a friendly interface, easy to use, and good performance in terms of compression rate and speed. It has a high compression ratio, and 3.x uses a more advanced compression algorithm, which is one of the formats with a larger compression ratio and faster compression speed. 3.3 Added the function of scanning the compressed file for viruses, decompressing the "Enhanced Compressed" ZIP archive, and upgrading the function of volume compression.
WinRAR has always had this advantage in the DOS era, and has been proven by many experiments that WinRAR's RAR format is generally 10%~30% higher than other ZIP formats, especially it also provides a selectable compression algorithm for multimedia data.
WinRAR can greatly improve the compression rate of WAV, BMP sound and image files with a unique multimedia compression algorithm, although we can convert WAV, BMP files to MP3, JPG and other formats to save storage space, but don't forget that WinRAR compression is a standard lossless compression.
Although other software can also support ARJ, LHA and other formats, it requires the DOS version of the corresponding software, which is really limited. But WinRAR is different, not only can it decompress most compressed formats, but it can also directly create ZIP compressed files without the support of plug-ins, so we don't have to worry about how to deal with ZIP format without other software.
We know that the inability to create multi-volume self-unpacking is a major drawback of some kind of compression software, but WinRAR is able to handle this kind of work with ease, and the self-unpacking files can be password protected.
