Maximum insertion size is several megabytes. Additionally to usual data erasures, the new recovery record is able to detect deletions and insertions of much larger size than in previous RAR versions. For single continuous damage 4.x and 5.0 efficiency is about the same. Smaller record, such as 1 - 2%, or less random damage type would result in less difference between 4.x and 5.0. If recovery record size is large enough, 5% and more, the new error correction scheme provides much higher resistance to multiple damages comparing to RAR 4.x recovery record. RAR 5.0 recovery record is based on Reed-Solomon error correction codes. Changes in RAR 5.0 archive format: a) file times are stored as Coordinated Universal Time (UTC) instead of former local time, making file exchange among several time zones more straightforward b) file names and archive comments use UTF-8 encoding. Though not to same extent as in compression algorithm, it improves the decompression speed on large files with poorly compressible data or when using BLAKE2 checksums. These excluded algorithms are not efficient for modern data types and hardware configurations e) RAR 5.0 decompression can utilize several CPU cores. If modifiers are not present, megabytes are assumed, so -md64m is equal to -md64 d) RAR 5.0 format includes Intel IA-32 executable and delta compression algorithms, but RAR 4.x text, audio, true color and Itanium algorithms are not supported. Append 'k', 'm' and 'g' modifiers to specify the size in kilo-, mega- and gigabytes, like -md64m for 64 MB dictionary. You can use "Dictionary size" archiving dialog option or -md switch to change this value c) -md switch syntax is modified to support larger dictionary sizes. Both 32 bit and 64 bit versions can unpack archives with any dictionary size, including 1 GB b) default dictionary size for RAR 5.0 is 32 MB, typically resulting in higher compression ratio and lower speed than RAR 4.x 4 MB. 32 bit WinRAR version can use up to 256 MB dictionary when creating an archive. Changes in RAR 5.0 compression algorithm: a) maximum compression dictionary size is increased up to 1 GB in 64 bit WinRAR. You can select "RAR" instead of "RAR5" option in archiving dialog to create RAR 4.x archives compatible with previous WinRAR versions. Older software including older WinRAR versions is not able to decompress RAR 5.0 archives, so if you plan to send an archive to other people, it is necessary to take the compatibility issue into consideration. You can use "RAR 5.0" option in archiving dialog or -ma command line switch to create RAR 5.0 archives. WinRAR - What's new in the latest version Version 5.00 1. It just nags you if you haven't purchased it I guess. A lot of people hate it's dated look but I don't mind it. Here shows 7-Zip and the new WinRAR 5 size. – WinRAR features are constantly being developed to keep WinRAR ahead of the pack.Update, 7-Zip still beats it but WinRAR 5 got better. Recovery record and recovery volumes allow to reconstruct even physically damaged archives. – WinRAR offers the ability to create selfextracting and multivolume archives. The number of archived files is, for all practical purposes, unlimited. – WinRAR supports files and archives up to 8,589 billion gigabytes in size. – WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits. This avoids confusion in the early stages of use. – WinRAR is easier to use than many other archivers with the inclusion of a special “Wizard” mode which allows instant access to the basic archiving functions through a simple question and answer procedure. – WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface. – WinRAR provides complete support for RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives. – Using WinRAR puts you ahead of the crowd when it comes to compression by consistently making smaller archives than the competition, saving disk space and transmission costs. The special compression algorithm compresses multimedia files, executables and object libraries WinRAR automatically recognizes and selects the best compression method. This will save you disc space, transmission costs AND valuable working time as well. By consistently creating smaller archives, WinRAR is often faster than the competition. WinRAR puts you ahead of the crowd when it comes to compression. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format. WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives. RAR files can usually compress content by 8 percent to 15 percent more than ZIP files can.
