File extension rar

File extension rar is one of the file extensions that define type of the file and its contents.

If you ever felt the need to compress a folder or file, you would definitely have come across .rar files. This type of file formats is extremely useful for compressing files. Technically, t he RAR files are the archived file formats of the WinRar archiver. These files support the features of compression of data files and error recovery. Thus, the files with .rar extension are the data containers, and store one or more files in a compressed or zipped form. Such files were invented by a Russian software engineer Eugene Roshal and thus, the name RAR stands for Roshal Archive. This software is licensed by win.rar.GmbH.

So, what does a user do with this type of file format?

After a file with the File extension rar is downloaded (which contains data in a compressed form) , the user has to unpack its contents so that they can be used. These files contain large amounts of data in a compressed mode and thus, it is necessary that all of the contained files should be unzipped and unpacked so that they can be used originally and individually. The compression ratio of a RAR file is higher and better than that of a ZIP file. The RAR files can also create multi-volume archives which are spanned and are split across other compressed files. Apart from the typical . rar extension, such files may also have extensions from .R00 to .R99.

The files with the File extension rar can be extracted and opened through various decompression programs. An example of such programs is the 7-Zip tool. Any such program will easily decompress the .rar files and will disintegrate the clubbed files contained in the parent file. After extraction, the smaller files can be easily used through different programs by double-clicking on them. The computer will itself find a suitable program to open such files. Some of these decompression softwares may also have the ability of creating the files with . rar extensions.

The latest version of the File extension rar format is the v5.0 which is the current version also and was implemented by Eugene Roshal. It is the new and improved version as it can accumulate the dictionary data of up to 1 GB. Also, it features higher compression and decompression speeds and enhances the multicore decompression support system. It also detects the duplication of a file and automatically removes text, multimedia and binary algorithms. Lastly, it also improves the recovery system of the computer to a great extent.
