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.
WinRAR 5.50 changelog:
- WinRAR and command line RAR use RAR 5.0 archive format by default. You can change it to RAR 4.x compatible format with "RAR4" option in archiving dialog or -ma4 command line switch. If you prefer RAR 4.x format by default, use "Create default..." button on "Compression" page of WinRAR settings and set "RAR4" in the displayed dialog. This change affects only new clean installs. If you already saved RAR format in the default compression profile in previous versions, WinRAR respects stored settings.
- Use "Set master password" button in "Organize passwords" dialog to encrypt saved password records and protect them from unauthorized access. If saved passwords are protected with master password, you need to enter the master password and press "OK" in password prompt to access them. If entered password does not match the master password, it is treated as a usual password for archive operations. Once entered, the master password is valid until WinRAR is closed. Close WinRAR and open it again after specifying the master password if you wish to see how protection works. Enter a valid and then empty master password to remove encryption from previously protected password records. This WinRAR version uses a new data format for password organizer, so passwords stored in "Organize passwords" dialog are not readable by older versions. It does not affect archive encryption formats and encrypted archives are compatible with previous WinRAR version. Organizer data is converted to a new format only when you save it and not immediately after installing WinRAR.
Prompt proposing to set the master password is displayed when storing a password in compression profile. You can enter the master password to encrypt password data stored in Registry and protect it from unauthorized access. You will need to enter the master password in password prompt dialog to access such compression profile after that. Once entered, the master password is valid until WinRAR is closed. Close WinRAR and open it again after specifying the master password if you wish to see how protection works. [full release notes]
