Someone sent me a .rar file and I can't open it, because it has a password. What are .rar files? How to open it?

RAR is a file format for data compression, similar to ZIP files. RAR stands for Roshal Archive; the format is named after its creator, Eugene Roshal.

A quick overview of file compression

File compression is a method of wrapping up one or more files into a single package that is often times smaller than the original(s). For example, say you wanted to e-mail a folder full of files to your friend. Instead of attaching the entire folder and all its multiple files to your e-mail message, you could compress the folder into one archive file and send that to your friend. You'll send the e-mail faster and your friend will download it quicker because the compressed archive is smaller than all of its contents in their original form. You can also be sure that your friend receives all of the files intended for him, because there's just one compressed file instead of many different files.



How to create and open .RAR files

In order to create (compress) and open (decompress) .RAR files, you need special software that understands the .RAR format. There are many software packages that can decompress .RAR files, but only the original WinRAR program can both compress and decompress with the .RAR format.
