Download WinRAR 3.91 Beta 1

RAR Labs has released the first beta release of version 3.91 of its RAR and WinRAR archiving tools. The popular compression tool is available for various operating systems, including Windows, Mac OS X and, in the future, Linux. The program can handle most common formats, including rar, zip, cab, arj, lzh, tar, gz, ace, uue, bz2, jar, iso, 7z and z, has a skinnable interface and support for Zip64 and multi- volume cab files. Besides some bug fixes, the most notable change in this release is support for z-zip archives created using the lzma2 algorithm. The full changelog of this first beta release is as follows:

Changes in WinRAR version 3.91 beta 1:

• This version can decompress 7-Zip archives created with LZMA2 algorithm.
• Now a password is requested only once when unpacking 7z archives with encrypted file names from context menu. WinRAR 3.90 asked it twice.
• This version can unpack tar.bz2 archives consisting of several smaller bz2 streams merged together. Previous versions unpacked only the first nested bz2 stream in such composite archive.
• WinRAR displays CRC32 or files inside of usual .gz (not .tar.gz) archives. Previous versions left this field blank for GZIP files.

Bug fixed:

• WinRAR 3.90 displayed “Save” button instead of “Open” or “OK” in “Find archive” dialog (“Open archive” command in “File” menu and “Browse…” command in archiving dialog);
• WinRAR could display incorrect file names when browsing malformed ZIP archives;
• WinRAR 3.90 failed to decompress LZH archives created with “-lh7-” algorithm;
• WinRAR 3.90 could fail to delete a part of files after archiving if delete to Recycle Bin was enabled. This bug was present when working in Windows XP, but not in Windows Vista and Windows 7;
• when unpacking ISO file using WinRAR “Extract files…” command in Explorer context menu, WinRAR could unpack same archived files twice during the same operation. It displayed the overwrite prompt when unpacking files for the second time;
• hexadecimal search in WinRAR 3.90 “Find” command and console RAR “ih” command failed to find matches if first byte in search string was greater than 127.
