Information:
1. WinRAR version for Windows x64 is available. If you use
Windows x64, it is strongly recommended to install 64 bit
WinRAR version. Itprovides a higher performance and better
shell integration than 32 bit version.
2. RAR compression speed is improved for multicore
and multiCPU systems.This improvement is most noticeable
in Windows Vista and Windows 7 operating systems.
3. "Remove duplicate folders from extraction path"option
in "Settings/Compression" dialog is replaced by more universal
"Remove redundant folders from extraction path"option.
This option will eliminate redundant archive name based folders
from extraction path if you unpack an archive with
"Extract toDestName" context menu command and if archive
root folder contains only one folder and no files.
4. Changes in "Extraction path andoptions" dialog:
a) "New folder" button creates a new subfolder in currently
selected folder;
b) F2 key renames a selected folderin the folders tree;
c) F5 key updated the tree pane contents;
d) Del key removes a selected folder in the folders tree.
5. You can enable "Showseconds" option in "Settings/File list"
dialog if you wish to see seconds in file dates in file list
in WinRAR shell.
6."Where to check for SFX archives" options group
in "Settings/Integration/Context menus items" dialog lets
you to controlprocessing of SFX archives in context menus.
For example, if you frequently right click ".exe" files
on slow network disks, you can turnoff "Network disks" options
to minimize the delay before displaying the context menu.
7. If you sort files by name in the file list inWinRAR shell,
WinRAR will use the new logical file name sorting,
same as in Windows Explorer, considering digits in file names
by their numerical value. Sofiles will be sorted as
1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt.
This new sort behavior is available in Windows XP Service Pack 2
andnewer.
8. 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.
9. New command line switch r disables recursion completely.
So ‘rar a r arc dirname’ command willadd only the empty
dirname folder and ignore its contents. By default, if dirname
does not include wildcards, RAR adds its contents even if
r switch is notspecified.
10. If used when extracting, the new command line switch ai forces
RAR to ignore file attributes. When using this switch,
extracted files willalways have attributes assigned by
operating system to a newly created file by default.
11. If output file name is not specified in "cw"command, console RAR
will send comment data to stdout.
12. When compressing stdin data with si switch, RAR sets
modification time of archived entry tocurrent system time.
Previous RAR versions did not fill this field, resulting in
meaningless modification time for stdin.
13. Message displayed when youplace the mouse cursor on WinRAR
tray icon includes the archive name now. Previously only
time left and total percent were displayed for archivingoperations.
14. Bugs fixed:
a) WinRAR could fail to open tar or tar.gz archive if such archive
contained a file larger than 8 GB;
b) WinRAR context menu didnot work properly in Windows 7 beta
if icons in context menus were enabled and user clicked
a file inside of Windows 7 Library folder;
c) previous WinRARversions failed to rename files having 5 or more
continuous spaces in the name. WinRAR shell does not display
such spaces for safety reasons, because theycan hide an actual
file extension. But this security measure prevented the rename
command to work properly.
