WinRAR 5.40

WinRAR Editor's Review

Winrar archiver is a powerful tool which allows you to create, manage, and control archive files.

It supports RAR and ZIP 2.0 archives, special algorithms optimized for text, audio, graphics, 32-bit and 64-bit Intel executables compression. You can now handle archives directly from Windows Explorer due to the shell integration including drag-and-drop facility and cascaded context menus. Winrar features wizards for beginners and command line interface for advanced users. It doesn't only open rar files, it can also handle non RAR archives (7-Zip, ACE, ARJ, BZ2, CAB, GZ, ISO, JAR, LZH, TAR, UUE, Z, GZip) management, solid archiving which can raise compression ratio by 10% - 50% over more common methods, particularly when packing a large number of small, similar files.

Using Winrar you can create multivolume archives, self-extracting archives (also multivolume) using the default or optional SFX modules. You can use a lot of service functions, such as encryption, archive comments, error logging, etc. Winrar has also an inbuilt viewer for viewing the content of text files within archives. You can create compression profiles in order to optimize your activity.

Winrar has a very friendly user interface, so that the menus are customizable and offer access to important archive commands like extract, test, comment, protect, and lock, but also other important tools such as scan, convert, or benchmark and hardware test.

Pluses: There are several versions of RAR, for a number of operating environments: Windows 32 bit and 64 bit, Linux, FreeBSD, DOS, OS/2, MacOS X. You can test, lock and repair/recover physically damaged archives or volumes allowing to reconstruct missing parts of multivolume archives. You can also take advantage of miscellaneous options such as Background archiving, turn PC off when done, compression estimation.

Among the new features of Winrar we may mention: new buttons (options) such as: "Define volume sizes...", "Rename automatically", "Multithreading" option added to "Benchmark and hardware test" command, new command lines, increased compression speed (5 -15%) for some data types. The publisher states that they fixed some bugs in the multithreaded text compression algorithm.

The speed versus the rate of compression came out as medium compared to WinAce and WinZip: a directory containing multimedia and text files in total size of 104 Mb compressed at a normal rate by Winrar resulted in a 64 Mb in 51 seconds compared to 76,2 Mb in 17 seconds for WinZip and 64,2 Mb in 1 minute and 11 seconds for WinAce.

Drawbacks / flaws:

In conclusion: A good compression over a quite short archiving time sets WinRAR in a very good position among the well known archivers. The program is a very good and reliable archiving solution.

You can download Winrar for free and within the free trial, you can use the program at it's full potential (free rar extraction, archiver, of many archive files and more). If you wonder about how to open rar files, this is one of the best rar opener and manager on the market.

What's New in Version 5.40 of WinRAR

1. "Name encoding" submenu in "Options" menu allows to select
encoding for archived file names. This selection affects archive
browsing and extraction commands. You can use Ctrl+E keyboard
shortcut to access this menu quickly.

It can be useful when unpacking an archive without Unicode file names.
For example, unpacking a zip file with Chinese archived names
in Windows with Russian specified as a language for non-Unicode
programs.

2. If RAR recovery volumes (.rev files) are present in the same folder
as usual RAR volumes, archive test command verifies .rev contents
after completing testing .rar files.

If you wish to test only .rev files without checking .rar volumes,
you can select .rev files in WinRAR file list and apply "Test"
only to them or run:

rar t arcname.part1.rev

in the command line.

3. While NTFS file system permits file names with trailing spaces
and dots, a lot of Windows programs fail to process such names
correctly. If "Allow potentially incompatible names" option
in "Advanced" page of extraction dialog is turned off, WinRAR removes
trailing spaces and dots, if any, from file names when extracting.

This option is turned off by default.

Command line RAR also removes trailing spaces and dots when extracting
unless -oni switch is specified.

4. Previously "Synchronize archive contents" update mode
(-as command line switch) aborted if some of archiving folders
could not be read. Now WinRAR continues performing the operation
and preserves archived files matching unreadable folders.

5. WinRAR Shift+Del delete command can be used to delete folders
containing non-standard file names with trailing spaces and dots.
Usual delete to Recycle Bin also as Shift+Del in previous WinRAR
versions cannot delete such folders.

Unlike Del command, Shift+Del removes files permanently,
they are not moved to Recycle Bin. No additional prompts are issued
for files with read-only and system attributes.

6. You can drag folders from folder tree panel and drop them to
other programs or Desktop to copy or unpack them. Drag the archive
icon in tree panel root to unpack the entire archive.

7. "New folder" button in extraction dialog proposes a new folder name
based on archive name instead of generic "New Folder".

8. Command line RAR version information:

a) if -iver switch is specified, RAR displays the version number
and quits. You can run just "RAR -iver";

b) "x86" or "x64" is displayed in Windows RAR version information
both for -iver and in the copyright title for other commands.

9. If -p switch is used without optional parameter,
a password can be also set with file redirection or pipe.

For example: rar -p myarc.rar myfiles < psw.txt

10. Command line RAR treats 'arcname.partN' as 'arcname.partN.rar'
if 'arcname.partN' does not exist and 'arcname.part#.rar' exists.

For example, it is allowed to run:

RAR x arcname.part01

to start extraction from arcname.part01.rar

11. Improvements in 7z archives support:

a) "Solid" status is correctly detected and reported for 7z archives
in WinRAR "Info" command;

b) dictionary size is displayed for LZMA and LZMA2 7z archives
in WinRAR "Info" command;

c) unknown packed size for files inside of 7z solid block is denoted
as '?' instead of '0' when browsing the archive contents in WinRAR.

12. Maximum comment length for RAR archives is increased from 64 to 256 KB.

Since SFX script commands are stored in archive comment,
it allows a longer main and license text in SFX archives.

13. Size of default WinRAR viewer font is scaled up properly
in Windows high DPI mode.

14. Switch -scul can be used to process big endian UTF-16 list files
as well, provided that they have a correct byte order mark.
Previously it allowed only little endian file lists.

15. Minimum supported Windows version is Windows XP SP3 now.
WinRAR will not run in Windows XP without service packs.

16. "Settings/File list/Allow all uppercase names" option is removed.
This option was intended to simplify transition from MS DOS to
Windows and is not needed anymore.

17. Bugs fixed:

a) WinRAR 5.31 x64 "Compress and email" command did not work
with Microsoft Outlook x64;

b) if WinRAR 5.31 version for one of right to left languages
was installed in Windows with English or other not right to
left system language, WinRAR could change Windows Explorer
layout to right to left;

c) if archive was stored in a folder without "Write" permission
and if archive contents was extracted with drag and drop to
a writable folder, WinRAR issued an unnecessary privileges
elevation prompt.
