Typically N% recovery record can repair up to N% of continuously damaged data and increases the archive size by only slightly more than N%.Ībility to fix multiple damages is proportional to N.

For RAR 5.0 archives the parameter of -rr switch and rr command is always treated as a percent of archive size regardless of presence of % character. So it is impossible to specify its size in sectors. New recovery record is not based on 512 byte sectors anymore and incorporates more complicated data structures. After successful archive repair, you may need to create a new recovery record for saved files. Note, though, that 'Repair' command does not fix broken blocks in recovery record. RAR 5.0 recovery record is more resistant to damage of recovery record itself and can utilize a partially corrupt recovery record data.

Thus, if you use some special software to copy an archive from damaged media, it is better to choose the mode, when damaged sectors are filled by zeroes or any other data instead of cutting them out completely from resulting file. Still, the best recovery performance and efficiency is achieved if no deletions and insertions are present, so all data including damaged sectors preserve their original positions. Maximum deletion size depends on the damage type and in some cases can be as large as the recovery record size. Maximum insertion size is several megabytes. For single continuous damage 4.x and 5.0 efficiency is about the same.Īdditionally to usual data erasures, the new recovery record is able to detect deletions and insertions of much larger size than in previous RAR versions. 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.

file names and archive comments use UTF-8 encoding.

file times are stored as Coordinated Universal Time (UTC) instead of former local time, making file exchange among several time zones more straightforward.

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.

RAR 5.0 decompression can utilize several CPU cores.

These excluded algorithms are not efficient for modern data types and hardware configurations

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.

If modifiers are not present, megabytes are assumed, so -md64m is equal to -md64 Append 'k', 'm' and 'g' modifiers to specify the size in kilo-, mega- and gigabytes, like -md64m for 64 MB dictionary.

-md switch syntax is modified to support larger dictionary sizes.

You can use 'Dictionary size' archiving dialog option or -md switch to change this value

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.

#Winrar 5.00 64 Bit#

Both 32 bit and 64 bit versions can unpack archives with any dictionary size, including 1 GB 32 bit WinRAR version can use up to 256 MB dictionary when creating an archive. maximum compression dictionary size is increased up to 1 GB in 64 bit WinRAR.Changes in RAR 5.0 compression algorithm:.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. Dit formaat, dat rar 5.0 gedoopt is, levert over het algemeen kleinere archieven op, maar dit gaat wel ten koste van de snelheid van het in- en uitpakken. De belangrijkste verandering in versie 5.00 is de introductie van een nieuw compressieformaat. Het programma kan overweg met de meest gangbare formaten - waaronder rar, zip, cab, arj, lzh, tar, gz, ace, uue, bz2, jar, iso, 7z en z - heeft een aanpasbare interface, en heeft ondersteuning voor Zip64 en multivolume-cab-bestanden. De populaire compressietool is beschikbaar voor diverse besturingssystemen, waaronder Windows, Linux en OS X.

RAR Labs vond het na acht bètareleases welletjes en heeft de final release van versie 5.00 van zijn archiveringsprogramma's RAR en WinRAR uitgebracht.
