Update: 7-Zip 4.63

Friday, January 2nd, 2009

The last day of 2008 brought, aside new year’s resolutions, a new version of 7-Zip: 4.63.

The only update worth mentioning is the support for unpacking ZIP archives encrypted with the AES algo (PKWARE-AES, implemented in PKWARE’s PKZIP and SecureZIP products).

AES is a very fast encryption algorithm standardized in 2002. It can be used with 128,192 and 256-bit encryption keys. All of these are available in PKWARE-AES.

Sunday, November 23rd, 2008

The fourth 7-Zip beta in a row after the last stable version (4.57) is now out.

Beside some bugfixes and a new localization, 7-Zip 4.61 beta adds LZMA support to ZIP archives (both reading and creating them).

LZMA is the compression algorithm used by default in the 7z format and provides better results compared to ZIP’s DEFLATE.

WinRAR embarks on the Vista wave!

Tuesday, January 16th, 2007

WinRAR 3.71 Screenshot It was high time WinRAR joined the Vista-compatible club, and this new beta accomplishes just that.

WinRAR 3.71 Beta 1 packs a host of changes, many of which aim to make the program more compliant to the Windows Vista standards. This is obvious if we take a look at the new help facility, which dropped the old HLP format in favor of the (not-so-new-anymore) CHM system, a change that does not affect the program’s functionality, but was demanded by the Vista guidelines.

The other changes are, however, more noticeable. WinRAR now complies to the new security model and makes use of the administrator permission dialogs Vista users are already accustomed with. Logfiles, themes, settings and regkeys are now stored by default in the %APPDATA%\WinRAR folder, which is the preferred method in Vista (still, users can specify a different, custom folder).

From the non-Vista-related changes crowd the following stand out: UDF support for the ISO format, Unicode support for filenames in ISO images, design changes in the “Extract” dialog and a stack overflow fix.

Downloads and useful links follow. The detailed list of changes in this release is also included.

*** WHAT’S NEW IN WINRAR 3.71 BETA 1 ***

1. Numerous Windows Vista compatibility changes:

a) help format changed from old HLP to newer HTML based CHM;

b) GUI self-extracting modules attempt to request for
administrator permissions if they cannot create destination
folder under current user account;

c) Log file rar.log and WinRAR theme files are stored
in %APPDATA%\WinRAR folder instead of WinRAR program files folder.

Exported settings file settings.reg is also stored
in %APPDATA%\WinRAR folder by default, but it is possible to
select another folder in “Save WinRAR settings” and “Load WinRAR
settings” dialogs.

WinRAR searches for registration key and settings.reg
both in its program files folder and in %APPDATA%\WinRAR;

d) Vista compatibility changes in WinRAR shell integration.

2. Added support for ISO 13346 (UDF) file format. This format
is frequently used in ISO images of DVD disks.

3. Added Unicode support for ISO 9660 files, so WinRAR should
handle non-English file names in .iso files better.

4. Design changes in window displaying archiving and extraction
progress:

a) it provides more space for file names, allowing lengthy names;

b) it displays the current archive name in separate line,
allowing much longer archive names than before;

c) when archiving, it displays the current compression ratio
in separate line;

d) it can use both standard Windows and classic WinRAR progress bars.
Turn on “Windows progress bars” option in WinRAR “Settings/General”
dialog to use standard progress bars. By default this option is
on if some Windows visual style is active and off if Windows Classic
theme is selected.

Windows progress bars are two color only, so they do not indicate
the current compression ratio. But now the ratio is displayed
in separate line;

e) “Mode…” button moved to bottom of window.

5. GUI self-extracting modules support following command line
switches:

-d set the destination path
-p specify a password
-s silent mode, hide all
-s1 same as -s
-s2 silent mode, hide start dialog
-sp specify parameters for setup program

6. GUI self-extracting modules do not pass the entire command line
to setup program like they did in previous versions.
If you need to get access to entire command line of SFX archive,
parse sfxcmd environment variable which contains this command line.

7. New switch -sc[objects] allowing to select character
sets for archive comments and list files. It replaces -fcu switch
introduced in RAR 3.60, which was removed from list of supported
switches. Now you need to specify -scuc instead of -fcu to use
Unicode comments. Unlike -fcu, -sc also supports OEM and ANSI charset.

8. New “Save archive copy as…” command in “File” menu.
This command may be useful if you opened an archive from Internet
directly in WinRAR and then decided to save it on local disk.

9. “Word wrap” command added to “View” menu of WinRAR internal viewer,
so you can change the wrapping mode of already opened viewer window.

State of this option is not stored between viewing sessions.
If you need to change the default word wrap mode, use WinRAR
“Settings/Viewer” dialog.

10. Buttons “Up” and “Down” added to “Organize profiles” dialog.
Using these buttons you can change position of selected profile
in the list.

11. Operation progress is displayed when adding the recovery record.

12. If WinRAR is minimized to tray and mouse is over its icon,
WinRAR diplays a message about the current operation progress.
In previous versions it included only percent done, now it also
contains the time left information.

13. Console RAR displays “Calculating the control sum” message
when calculating CRC32 control sum for newly created RAR volume.
Previous versions also calculated the volume control sum,
but did it silently.

14. Archives history list in “File” menu allows Unicode names,
providing more reliable support for non-English archive names.

15. Stack overflow vulnerability has been corrected in password
processing module of console RAR and UnRAR. GUI WinRAR is not
affected. We are thankful to the iDEFENSE LABS for reporting this bug.

WinRAR 3.62 fixes 7-Zip archive handling vulnerability

Tuesday, December 5th, 2006

WinRAR 3.62 Screenshot WinRAR 3.62 is a release clearly dedicated to improving modules that handle third-party compression formats, 7z and gzip to be more precise.

The fix for 7-Zip’s format is the most notable since it targets a stack overflow vulnerability.

The bug in gzip handling was, at most, an inconvenience: sometimes the date for an extracted file could be set incorrectly.

Apparently, these flaws affected only the Windows build of WinRAR, since the version numbers for the Linux, BSD and Mac OS X build are the same (3.60).

*** WHAT’S NEW IN WINRAR 3.62 ***

- Stack overflow vulnerability has been corrected in WinRAR module processing 7-Zip archives;
- WinRAR GZip module could set a wrong file date when unpacking GZip archives.

WinRAR 3.61 plays nicer with Windows 95

Thursday, September 14th, 2006

WinRAR 3.61 ScreenshotWinRAR 3.61 has been posted today on the Rarlab download site. Only the Windows GUI and command line versions have been updated. The DOS, Mac OS X, Linux, FreeBSD ports are still at 3.60.

This is basically a bugfix release - it addresses a flaw in the multithreaded text compression module. Singlethreaded mode and other platforms than Windows were not affected.

Another issue that was fixed prevented WinRAR 3.60 from running on Windows 95. (It’s nice to see that, even mother Microsoft has banished its sibling - Win95 -, software developers strive to continue supporting their software on this platform.)

See below for the full changelog information.

*** WHAT’S NEW IN WINRAR 3.61 ***

- Corrected a bug in multithreaded text compression module, which under some circumstances might result in corrupt archived data.
This bug was present only in multithreaded mode and only in WinRAR 3.60. RAR versions for other platforms are not affected.

- Resolved a compatibility issue preventing WinRAR 3.60 to run in Windows 95.

WinRAR 3.60 Finally Released: Multithreaded, Faster, Folder Tree Panel

Wednesday, August 16th, 2006

WinRAR 3.60 Screenshot The final version of WinRAR 3.60 is out now! Here’s a download link to feed the impatient (MS-DOS, MacOS X, Linux, FreeBSD, PocketPC).

WinRAR 3.60, the compression giant’s latest stable version since 3.51, brings forth several new features such as multithreading support for multiprocessor/hyperthreading/dual-core computers, up to 15% compression speed boost, explorer-style treeview panel for both file and archive mode, command line archive conversion.

Other various improvements (see full list of changes below) target archive handling and manipulation, LZH/lh7 decompression support, better benchmark tool options and several command line commands and switches.

The Linux, FreeBSD, MacOS X and PocketPC ports have been updated as well to version number 3.60.

*** WHAT’S NEW IN WINRAR 3.60 FINAL ***

1. Multithreaded version of RAR compression algorithm improves
the compression speed on computers with several CPU,
dual core CPU and processors with hyperthreading technology.
Multithreading is enabled by default, but you can disable it
in “General” part of “Settings” dialog.

In the command line mode you can control multithreading with
-mt switch.

2. WinRAR can display the folder tree panel allowing to navigate
in disk and archive folders. Use “Options/Folder tree” submenu
to enable the folder tree. It can be configured separately
in file and archive management modes.

Folder tree replaces “Browse for folder” command previously
available in “File” menu and uses its Ctrl+T keyboard shortcut.

3. Now WinRAR “Rename” command also works with ZIP archives.
Previous versions could rename files only in RAR archives.

4. Added decompression of LZH archives created with “-lh7-” algorithm.

5. New “Remove duplicate folders from extraction path” option
in “Settings/Compression” dialog.

If this option is on and you unpack an archive which root folder
has no files and only one ’somename’ folder and if destination
folder is new or empty and also ends with ‘/somename’, WinRAR
will exclude one ’somename’ from resulting ’somename/somename’ path.

6. New “Define volume sizes…” button in “Settings/Compression”.
This button activates “Define volume sizes” dialog. Here you
can customize the list of predefined volume sizes associated
with “Split to volumes, bytes” field in archiving dialog.

7. Speed of RAR general compression increased for some data types.
Depending on data type and size the gain may achieve 5 - 15%.

8. New “Rename automatically” option in the extraction dialog
and command line -or switch to rename extracted files automatically
if file with the same name already exists. You can also enable
the auto-renaming mode directly from the overwrite confirmation
prompt with “Rename All” button.

Renamed files will get names like ‘filename(N).txt’,
where ‘filename.txt’ is the original file name and ‘N’ is a number.

9. “Set modification time” option in “Advanced” part of extraction
dialog is accessible also for ZIP archives. Previously it could be
changed only for RAR archives.

10. “Multithreading” option added to “Benchmark and hardware test”
command, so you can compare performance of usual and multithreaded
versions of RAR compression algorithm.

11. New ‘ch’ (change archive parameters) command line mode command.
Its purpose is to apply switches like -av, -tl and -cl to archive.

12. New ‘cv’ command line mode command. It provides the command line
interface to WinRAR “Convert archives” command. It is supported
only by winrar.exe, not by rar.exe.

13. New command line -sl and -sm switches to set size
limits of processing files.

14. New command line -fcu[file] switch allows to read archive
comments from Unicode files. It also modifies behavior
of “cw” command, setting the comment output format to Unicode.

15. 7Z added to list of formats stored without compression
when using -ms switch without a parameter.

16. Switch -e[+] is now supported by most of command line
operations including extracting and deleting files. Previously
it was supported by only archiving command.

17. It is allowed to use environment variables in archive name
in archiving dialog, in destination path in extraction dialog,
in folder names on “Compression” and “Paths” pages in WinRAR
settings. For example, you can enter ‘%temp%’ in “Folder for
temporary files” field.

WinACE gets update. And Adware.

Tuesday, August 1st, 2006

WinRAR Free This is not so fresh but I couldn’t miss it and neither can you: WinACE got updated on the 12th of July to version 2.65.

Apparently, this release brings only a “new option for licensing your copy of WinACE”. This is how the developers call it; I call it adware supported software. Either way, what it all boils down to is this: if you want to legally use WinACE you can either go the “old way” and buy a license for 29 bucks or the “new way” by installing a “consumer utility that delivers relevant advertisements, exclusive offers and money saving coupons based on the web content that interests you”, namely the notorious WhenU Save adware thingy (check the link for some info).

Good? Bad? Well, in my opinion, it’s not going to make too much of a difference and here’s why: nobody wants adware on their computer, except the so-called “non-tech-inclined” people (also refered to as lazy or ignorant) since they might not have a clue about what those nice and shiny popup offers really do (invade privacy by tracking web browsing patterns, in short). But then again, these “not-computer-proficient” boys and girls don’t normally end up working with WinACE, they generally use the ZIP capabilities integrated in Windows or WinZIP.

I believe that advanced users don’t count in this situation - they’re going to buy it or crack it as they did before.

I wonder what will be the outcome of this for e-merge GmbH and WinACE, if the association between them and “partner WhenU” (quote) will somehow hurt their image.

When you first run WinACE 2.65 you are prompted to read some shareware information that states that the software is fully functional for 30 days, after which you will either have to purchase a license or get a free one by “installing an advertising-related software product”. You are warned that if you uninstall the adware, the “free” license will become void. WhenU Save is not included in the standard WinACE installation kit - it has to be downloaded from the Internet. The download and install process can be initiated from the shareware notice window itself. I tried to see how it works, but it hanged and the download step, although my firewall was not configured to block WinACE’s access to the Net.

Free WinRAR Registrations. Get it Quickly - Offer Starts and Ends Today!

Sunday, July 30th, 2006

WinRAR Free The greatest archiving utility in the whole world has done it again: WinRAR 3.51 won the 2006 “SIAF People’s Choice Award for Best Overall Utility“. The “Best Overall Utility” award was won by WinZip.

To express their hapiness towards this, as well as their thanks to all the people who voted for WinRAR, RarLab decided to have a 1-day offer of free registration keys for WinRAR 3.51.

All you have to do is fill in a simple form and you will receive your registration key by email. Registering will automatically place you in a mailinglist about the latest WinRAR releases and offers, but you can opt-out once you receive the first email. You may also choose to receive similar offers about software recommended by RarLab, if you are interested.

Keep in mind, though, that this is a non-upgradeable reg key, which only works with WinRAR 3.51, thus it will not be valid for the upcoming stable release of WinRAR 3.60 (currently Beta 8).

If all of the above is ok with you, hurry and get your key while the offer is still on. There are a lot of people interested in getting a free license (can’t say I’m amazed, WinRAR is an excellent utility), which kind of overloaded the win-rar.com website. You might need to try a few times to get in and submit the form correctly. Rest assured, though, that once you send the form, you will get the registration key.
