WinRAR 5.00 Beta 8

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 8:

  • WinRAR treats files with .txz extension as .tar.xz archives.
  • If 7-Zip archive extraction is cancelled, WinRAR deletes the incompletely extracted file. Previous versions did not delete it.

Bugs fixed:

  • solid archive updating was aborted for archives containing BLAKE2 checksums;
  • folder tree panel did not allow to go to the archive root folder;
  • "Reuse existing window" option did not work if first WinRAR copy was browsing an archive and second WinRAR copy attempted to open another archive in another folder;
  • "Advanced compression parameters" dialog settings format in Registry was incompatible with WinRAR 4.20.

Sadly it's just not about icons, it's the whole look and feel of the application. Always loved WinRAR, just time for UI work!

the whole layout is outdated, so changing icons doesn't really help much, especially if available themes look just as outdated.

Nice, but after all these years the UI needs a modern touch.
Just a pinch, nothing 'revolutionary' as apple would make it sound.
I know about themes, i don't like themes, i never use themes to any of my programs. I like it native and default

WinRAR's partially extracted file deletion was always annoying, with no way to turn it off. Sometimes partially extracted video files still play just fine up till the cutoff point.

That's why I prefer 7zip.

If you check that option and click the 'Save Settings' button it'll be checked by default in future.

Why would you ever want to do that? Filling hard drives with corrupted duplicated files has always been everyone's dream!

Which is good - not wasting any time trying to fix what's not really broken, just ugly (there's theming support for those ugly icons, so that ugly doesn't really count).

And to be fair, I don't need from WinRAR more than its context menu. I've got the default profile set appropriate for most tasks.

Anyway, I find it great that they are releasing many betas instead of 5.0, 5.01, 5.x final, but bug-ridden releases. A matter of nomenclature, but this is how it should be everywhere and absolutely isn't.
