RAR uses the filename extension '.rar' for data volume sets and '.rev' for recovery volume sets.

RAR is typically more effective at data compression than ZIP's default support. It's a WinRAR archiver's native file format for storing multiple files in compressed form. Unlike regular folders on your hard drive, RAR files require third-party software to access and extract the archive's contents. It is a collection of one or more files or directories. A compressed file is a type of archive file that is proprietary. The acronym RAR refers to Roshal Archive. Since the files in a ZIP archive are compressed separately, they may be extracted or replaced without compressing or compressing the entire library. Because each file is kept individually, various files in the same archive can be compressed differently.

ZIP allows you to compress your files in a variety of ways, as well as just store them without squeezing them. Multiple files can be stored in.ZIP archives. Several techniques, including LZMA, WavPack, PPMd, BZIP2, DEFLATE, and others, can be used to compress or zip multiple files. On the other hand, ZIP archives can do more than compress data they can also encrypt (password-protected) files and divide archives with only a few clicks. ZIP files are data containers that use Zip compression to enclose one or more files in a compressed or zipped manner. The most incredible thing is that ZIP files may be opened by any application that produces them. ZIP is a popular format supported by several software tools, including Microsoft Windows and Mac OS X's built-in ZIP support.

This file format was created in 1989 by Phil Katz. ZIP is a file format for archiving and lossless data compression.
