WinRAR

WinRAR is a file-archiving utility for creating and extracting RAR archives and working with other archive formats. It also supports compression, encryption, recovery records, and splitting archives into volumes.

RAR file format: RAR is a proprietary archive format that stores compressed files and supports features such as encryption and recovery records. WinRAR’s native format defines the archives it creates and extracts.
ZIP (file format): ZIP is a widely supported archive format that stores files with optional compression and encryption. WinRAR can create and extract ZIP archives as an alternative to RAR.
Eugene Roshal: Eugene Roshal is a Russian software developer known for creating the RAR archive format and WinRAR. Roshal created the format and utility at the center of WinRAR’s history.
7-Zip: 7-Zip is a free, open-source file archiver that creates 7z archives and handles many other formats. 7-Zip competes with WinRAR and creates 7z archives rather than RAR files.
Data compression: Data compression encodes information using fewer bits than its original representation. WinRAR reduces archive size through compression algorithms.
7z: 7z is an archive format associated with the 7-Zip utility and supports several compression methods. WinRAR can extract 7z archives, though 7z is a competing native format.
RAR: RAR is an archive format and compression algorithm developed by Eugene Roshal. WinRAR is the principal utility for creating RAR archives.
PeaZip: PeaZip is a free, open-source file archiver with support for numerous archive formats. PeaZip offers a cross-platform alternative to WinRAR’s archive management.
Solid compression: Solid compression processes multiple files as a continuous data stream to improve compression when files share patterns. RAR solid archives can compress related files more efficiently than treating each separately.
Self-extracting archive: A self-extracting archive is an executable file that contains compressed data and extraction software. WinRAR can package archives as executables that extract without a separate archiver.
