Description

A RAR file, just like zip, is an archive file that can contain one or more files and can use a compression algorithm to achieve a smaller file size. Rar, named after its inventor Yevgeny Roschal, stands for Roshal ARchive. The Rar compression algorithm is not free of license fees, so RAR can only be created from the commercial products of the manufacturer Rarlab down to a few commercial alternatives.

However, the Rar archive unpacking algorithm is royalty free, so unpacking a RAR archive is supported by almost any multiformat packager and on a variety of operating systems. To create one needs depending on

Operating system the programs WinRAR (for Windows), RAR for DOS, RAR for Linux, UnRarX for Macintosh.

The Rar format offers archive encryption with AES (up to 256 bit) as well as file name encryption.

So it is not possible for an unauthorized person to unpack the content nor to see from the filenames what the content is. Rar also offers the distribution of large amounts of data into several files, which then end in r00, r01, r02

or also rar.part1, rar.part2 etc. It also offers additional security mechanisms for shared archives.

Since there are different versions of the RAR formats, it may happen that a RAR archive does not appear to be unpackable. In this case you just need a newer version of the unpacking program. If in doubt, you should always try the latest version of the manufacturer's products, of which there are also trial versions.

The Rarformat has despite a mostly much higher compression rate than Zip only a medium distribution on the Internet experience, especially because of the commercial algorithm. On the other hand, Rar learns through the 7-Zip format, which is similarly good and better

Offers compression rates, from free side competition.

How to open a RAR file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the RAR file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a RAR file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support RAR files. At this point we are looking for disk space where the application was installed in and we can link it with a RAR file. Since then, our operating system will use the selected program to support all RAR files.

Other issues

Despite the described problem with RAR there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the RAR file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the RAR file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
