WinRAR is a powerful archiving tool which comes packed with essential functionality.
The program can open a lengthy list of archive file types, for instance: RAR, ZIP, 7-ZIP, ACE, ARJ, BZ2, CAB, GZip, ISO, JAR, LZH, TAR, UUE and Z. You can work in multiple ways, including a simple Wizard mode, a more capable graphical interface, even the command line. You're able to create self-extracting archives with ease, and if you ever encounter a damaged or corrupted archive then the program's recovery options may be able to reconstruct it.
The latest release extends this with the addition of a new RAR 5.0 format. This increases the default and maximum compression dictionary sizes, is easier to recover if the archive is damaged, and now supports AES-256 encryption, amongst other tweaks. Of course, as the format is brand new it's not yet supported by other tools, but you can also create regular RAR files if you need to share them with others.
Elsewhere, the maximum path in regular RAR and ZIP archives has been increased to 2048 characters.
There's new extraction-only support for XZ archives.
And a few features have been dropped. The release notes explain that the "authenticity verification feature did not provide the required level of reliability and was removed", for example.
Note this is the 64-bit version of WinRAR.
What's new in 5.10?
- Added extraction support for ZIP and ZIPX archives using BZIP2, LZMA and PPMd compression
- Added extraction support for 7z split archives (.7z.001, .7z.002, ...)
- Added support for AES-NI CPU instructions allowing to improve RAR encryption and decryption performance
- Default theme images are scaled up with better quality in high DPI display mode
- Environment variables, such as %temp%, can be used in "Files to add" field of archiving dialog
- Switch -ai can be used when creating RAR archive, so predefined values, typical for file and folder, are stored instead of actual attributes. Previously this switch could be used only when extracting.
