WinRAR 5.00 Beta 6

WinRAR is an archiving utility that completely supports RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives. It consistently makes smaller archives than the competition, saving disk space and transmission costs. WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits. It supports files and archives up to 8,589 billion gigabytes in size. It also offers the ability to create self extracting and multi volume archives. With recovery record and recovery volumes, you can reconstruct even physically damaged archives.

What's new in WinRAR 5.00 Beta:

  • New RAR 5.0 archiving format. You can use "RAR 5.0" option in archiving dialog or -ma command line switch to create RAR 5.0 archives.
  • 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 select "RAR" instead of "RAR5" option in archiving dialog to create RAR 4.x archives compatible with previous WinRAR versions.

Changes in RAR 5.0 compression algorithm:

  • maximum compression dictionary size is increased up to 1 GB in 64 bit WinRAR. 32 bit WinRAR version can use up to 256 MB dictionary when creating an archive. Both 32 bit and 64 bit versions can unpack archives with any dictionary size, including 1 GB;
  • 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. You can use "Dictionary size" archiving dialog option or -md switch to change this value;
  • RAR 5.0 decompression can utilize several CPU cores. 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. [FULL RELEASE NOTES]

What's new in Beta 6:

  • Fixed a bug in recovery record generation in RAR 5.0 archive format. Under certain circumstances previous beta versions could produce wrong recovery record data, inefficient to repair a corrupt archive. Such invalid recovery record can be identified with "Test" command, which issues "Recovery record is corrupt" warning for it.

Never understood why none of these programs group togeather archive parts in the explorer view

ie

Some file ----
Part 1
Part 2

Some other fie
Part 1
Part 2

Far easier than searching for the first part every time you want to extract a archive.

You don't have to start with part 1, just double click any part and WinRar will work out what it needs to do. As for explorer it always sorts everything correctly for me i.e. part1, part2, part3, ...

While I like 7-Zip I bought WinRAR 14 years ago and my license is still valid and it is still a great bit of software so I keep using it

Also a lot more people know/use rar files than 7z files in the business word and while 7-Zip can of course open rar files only WinRAR can create them.

I also find RAR5 to be better than 7z compression in both speed and compression levels however as RAR5 is only supported in WinRAR 5 nobody else can open them yet lol

We don't use RAR in my team at work and only either 7zip or zip because we really don't want to install shareware on recipient machines. I may try RAR5 though, but unless the extensions are now .rar5, this will become confusing and annoying fast during the transition period. And with old, lingering RAR installs everywhere, the transition could be years.
