WinRAR and the RAR file format evolved over time. Support for the archive format RAR5, using the same RAR files exentions as earlier versions, was added in files in the older RAR file format are now referred to as RAR4. WinRAR versions before 5.0 do not support RAR5 archives.
The RAR5 file format added some features, but removed comments for each file (though archive comment still remains), authenticity verification, and specialized compression algorithms for text and multimedia files. RAR5 also changed the file name for split volumes from "archivename.rNN" to "archivename.partNN.rar".
The RAR5 file format increased the maximum dictionary size to 1 GiB; 11 different compression directory sizes from 1 MiB to 1 GiB are available, with the default in version 5 increased from 4 MiB to 32 MiB, typically improving compression ratio. AES encryption, when used, was increased from 128- to 256-bit. Maximum path length for files in RAR and ZIP archives is increased to 2048 characters.[6]
Options added in v5 include 256-bit file-hashing algorithm instead of default 32-bit CRC32, duplicate file detection, NTFS hard and symbolic links, Quick Open record to allow large archives to be opened faster.[6]
Features:
- Packing (creation) of RAR or Zip archives.
- Unpacking of, BZIP2, CAB, EXIE, , ISO, JAR, LHA, RAR, TAR, UUE, XZ, Z, ZIP, ZIPX, 7Z, 001 (split) archives.

- Multithreaded CPU compression and decompression.
When creating RAR archives:
- Support for maximum file size of 16Eib (264 bytes) minus 1.
- Compression dictionary from 1 MiB to 1 GiB (limited to 256 MiB on 32-bit Windows, however 32-bit Windows still can decompress archives with 1 GiB dictionary). Default size is 32 MiB.[6]
- Optional 256-bit BLAKE file hash can replace default 32-bit file checksum.
- Optional encreption using (Advanced Encryption Standard) with a 256-bit key.
- Optional data is provided in the form of recovery records and recovery volumes, allowing reconstruction of damaged archives (including reconstruction of entirely missed volumes).
- Optional "Quick Open Record" to open RAR files faster.
- Ability to create multi archives
- Ability to create files. The self-extractor can execute commands, such as running a specified program automatically after self-extraction.[11]
- Support for advanced NTFS file system options, such as NTFS hard and symbolic links.
- Support for maximum path length up to 2048 characters (stored in the UFT-8 format).
- Optional archive comment (stored in the UTF-8 format).
- Optional file time stamp preservation: creation, last access, high precision modification times.
- Optional files deduplication.
Operating systems support
As with most software, the latest archive tools no longer support older operating systems. The following historical information is useful for supporting older versions of Windows (including Wine on Linux) and MS DOS.
- WinRAR v5.x (current version) supports Windows XP and later.
- WinRAR v4.11 is the last version that supports Windows 2000.
- WinRAR v3.93 is the last version that supports Windows 95, 98, ME,
- RAR v3.93 is the last version that supports MS DOS and on 32-bit CPU, such as 80386 and later. It supports long file names in a Windows DOS box (except Windows NT), and uses the RSX DPMI extender.
- RAR v2.50 is the last version that supports MS-DOS and OS/2 on 16-bit CPU, such as 8086 and 80286
