WinRAR 4.20 Download For Pc

WinRAR is a shareware file archiver and data compression utility developed by Eugene Roshal and distributed by Ron Dwight, first released in autumn of 1993. It is one of the few applications that is able to create RAR archives natively, because the encoding method is held to be proprietary.

WinRAR supports the following features:
Complete support for RAR (WinRAR native conversion format) and ZIP archives
Multithreaded compression
The ability to create self-extracting and multi-volume (split) archives.
Data redundancy is provided via recovery records and recovery volumes, allowing reconstruction of damaged archives.
Support for advanced NTFS file system options and Unicode in file names.
Optional archive encryption using AES (Advanced Encryption Standard) with a 128-bit key.
WinRAR Unplugged is a portable version of WinRAR that does not require installation or create dependencies on the host computer.

Below is a summary of version information. Version 2.00 was released on September 6, 1996.
Since version 2.90, the new RAR3 archive format is implemented. The new compressed archives cannot be managed by old versions of WinRAR.
Since version 3.50, WinRAR adds support for interface skins and themes and support Windows XP x64.
Since version 3.60, WinRAR includes a multithreaded version of the compression algorithm, which improves compression speed on systems with multiple, dual-core, or Hyper-threading-enabled CPUs.
Since version 3.70, WinRAR features support for Windows Vista.
Since version 3.80, support for ZIP archives, which contain Unicode file names in UTF-8.
Since version 3.90, WinRAR adds support Windows x64 natively and support Windows 7. Also it enhanced support for multithreading.
Version 4.00 speeds up decompression by up to 30%. Windows 98, Windows Me, and Windows NT are no longer supported; the minimum Windows version required is Windows 2000.
Since version 4.10 WinRAR removes all ZIP limitations now allowing unlimited number of files and archive size. WinRAR now also allows to create multivolume ZIP files. ZIP archives now include Unicode file names.
Since version 4.20 Compression speed in SMP mode has been increased significantly, but this improvement was made at the expense of increased memory usage. ZIP compression now uses SMP as well. The default SMP mode cannot handle text; text compression is significantly worse unless additional switches are used. Also, Windows 2000 compatibility was removed.
