How to open RAR files
Did your computer fail to open a RAR file? We explain what RAR files are and recommend software that we know can open or convert your files.
What is a RAR file?
The RAR file extension indicates to your device which app can open the file. However, different programs may use the RAR file type for different types of data.
We are aware of 2 different uses of the RAR extension, which you can read more about below.
RAR Compressed Archive
Files that use the .rar file extension are archive files that have been created by the WinRAR file archiving software. The WinRAR application takes large files or collections of files and compresses those files into a single archive file.
Compressed files make it easier for users to share files via email and over the Internet. For example, if you needed to email multiple file attachments to an individual, you could compress them into a single RAR file, sending one attachment rather than many.
When the WinRAR archiver creates an archive, the resulting archive file is given the .rar file extension. RAR files are very similar to ZIP files but WinRAR uses a different compression algorithm, often resulting in smaller files.
