win.rar GmbH and RARLAB are proud to announce the first beta version of the new WinRAR 3.90.

Highlights of the 3.90 (beta 1) release are:
The new version of WinRAR makes this leading compression software ready for Windows x64. For all Windows x64 users it is strongly recommended to use 64 bit WinRAR version. It provides higher performance and better shell integration than the 32 bit version. Following closely the latest hardware developments, WinRAR performance in Windows Vista has been improved for systems with quad (or more) core CPUs to speed up considerably the compression time.

Furthermore the usability of the graphic interface has been improved and new commands for the command line mode have been added. For example the new command line switch -ai forces RAR to ignore file attributes stored in archive when extracting, so that the extracted files will have attributes assigned by the operating system to a newly created file by default. Also a new command line switch -r- disables the recursion completely, so 'rar a -r- arc dirname' command will add only the empty dirname folder and ignore its contents.

Other highlights in the new 3.90 (beta 1) include:

  •         Remove duplicate folders from extraction path" option in "Settings/Compression" dialog is replaced by more universal "Remove redundant folders from extraction path" option.
  •     Changes in "Extraction path and options" dialog like "New Folder" button, which creates a new subfolder in the folders tree; F2 key which renames a selected folder, F5 updates the tree content, and Del key removes a selected folder.
  •     User can enable "Show seconds" option in "Settings/File list" dialog if she/he wishes to see seconds in file dates in file list in the WinRAR shell.
  •     "Where to check for SFX archives" options group in "Settings/Integration/Context menus items" dialog lets the user control processing of SFX archives in context menu.
  •     If you sort files by name in the file list in WinRAR shell, WinRAR will use the new logical file name sorting, same as in Windows Explorer, considering digits in file names by their numerical value.
  •     Ctrl+W key combination can be used to close the main WinRAR window also as WinRAR viewer windows. "View as Windows text" shortcut in WinRAR viewer changed from Ctrl+W to Ctrl+I.

Also here are the bugs that have been fixed in the 3.90 (beta 1) version:

  •     WinRAR context menu did not work properly in Windows 7 beta if icons in context menus were enabled and user clicked a file inside of Windows 7 Library folder;
  •     previous WinRAR versions failed to rename files having 5 or more continuous spaces in the name. WinRAR shell does not display such spaces for safety reasons, because they can hide an actual file extension. But this security measure prevented the rename command to work properly.

These are just some of the features that have been added or improved. More information on all of the 14 improved items can be found here
Of course, as always, the upgrade to 3.90 is absolutely FREE for all registered users! Upgrading is quick and easy. Users only need to download and install the newest version of WinRAR to continue using the best compression tool around! No complicated uninstalling of the previous version is necessary.
