as earlier versions, was added in version 5.0; the older RAR file format has since been referred to as RAR4. WinRAR versions before 5.0 do not support RAR5 archives; only older versions of WinRAR run on Windows versions prior to Windows Vista, and cannot open RAR5 archives. The RAR5 file format increased the maximum dictionary size to 1 GB; 11 different compression directory sizes from 1 MB to 1 GB are available, with the default in version 5 increased from 4 MB to 32 MB, typically improving compression ratio. AES encryption, when used, is in

file-hashing algorithm instead of default 32-bit CRC32, duplicate file detection, NTFS hard and symbolic links, and Quick Open record to allow large archives to be opened faster. The RAR5 file format 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".
