Version 3.00
1. We introduced WinRAR 3.0 discount program, so a single user
license now is only $29.
As always, already registered users do not need to pay again.
RAR 1.x - 2.x registration is valid for 3.0 too.
New international RAR site is www.rarlab.com. You may visit it
to download latest versions and register RAR.
Also do not forget that we have a lot of regional sites processing
RAR registrations. Complete list is available in rar_site.txt.
2. Compression algorithm improved. Changes include:
a) dictionary size is increased to 4 MB, this helps to increase
compression on large data sets;
b) a special algorithm for text data, based on Dmitry Shkarin's
PPMII sources: ftp://ftp.elf.stuba.sk/pub/pc/pack/ppmdh.rar
We express our sincere gratitude and respect to Dmitry for
his excellent PPMII;
c) special preprocessing algorithms for 32-bit x86 executables,
Itanium executables, true color data, audio data and tables.
In many cases significantly increasing compression;
d) now RAR chooses the best combination of algorithms automatically,
so "Multimedia compression" mode and switch -mm are obsolete.
By default, RAR uses only the general compression algorithm
in the "Fast" and "Fastest" compression methods (-m1 and -m2),
advanced algorithms such as audio and true color processing are
enabled only in "Normal"..."Best" (-m3..-m5) modes, the advanced
text compression is activated only in "Good" and "Best"
compression (-m4..-m5). This default can be overridden using
the -mc switch.
RAR 3.0 archives can be unpacked by any RAR version beginning
from RAR 2.9, currently it is 2.9 and 3.0. RAR 3.0 can unpack
archives created by all older RAR versions.
3. Encryption algorithm is changed to AES (Advanced Encryption Standard)
with 128 bit key length.
4. Francesco Indrio ,
has once again done a nice job redesigning WinRAR graphics.
5. "Wizard" command helps novice users to perform basic
archive operations in simple, step by step mode.
Just click on Wizard button on the toolbar and choose
an operation which you want to perform.
6. "Send archive by email" option in the "Files" part of archiving
dialog. Your email program must support MAPI interface,
otherwise this option will not work.
In the command line mode you may use -ieml[.][addr] switch
to send a created archive by email.
7. WinRAR adds "Compress and email" item to Explorer context menu.
8. Default volume naming scheme is changed from volname.rar,
volname.r00, ..., to volname.part001.rar, volname.part002.rar, etc.
Switch -vn and "Old style volumes names" option in the archiving
dialog allow to use the old extension based scheme.
9. Added support of so called recovery volumes (.rev files),
which can be used to reconstruct missing files in a volume set.
One .rev file allows to reconstruct one missing RAR volume,
for example, 5 .rev files are able to reconstruct any 5 volumes.
In WinRAR you may create recovery volumes either specifying
their number in the archiving dialog or using "Protect" command
inside of the first volume.
In the command line RAR it can be done by the command 'rv[n]'
or switch -rv[n].
RAR and WinRAR automatically use .rev files to reconstruct
missing volumes when unpacking or testing a volume set.
It is also possible to double click on .rev file in WinRAR shell
or use the command 'rc' in the command line to force reconstructing.
I wish to thank developers of Mirror program, who invented
this idea and proposed to implement it in WinRAR.
10. SFX modules:
a) Windows SFX modules now support archives larger than 4 GB
and Unicode names;
b) It is possible to replace the standard SFX icon with your own.
Just specify the icon file name in "Load SFX icon from the file"
field of "Advanced SFX options/Text and icon" dialog.
c) new "Shortcut=DestType,SrcName,DestFolder,Description"
SFX script command allows to create shortcuts to unpacked
files on Desktop, Start Menu, Start Menu/Programs or Startup.
This feature is also available through "Shortcuts" list
in the "Advanced SFX options" WinRAR dialog;
d) modified syntax of TempMode SFX script command. It now uses
comma instead of '@' as a question and title separator.
It is important only for those users, who write SFX script
manually instead of specifying SFX parameters in WinRAR
"Advanced SFX options" dialog;
e) "Delete" SFX script command and "Files to delete" field
in "Advanced SFX options" dialog may include wildcard masks.
For example:
Delete=*.tmp
f) removed "Allow external signature" advanced SFX option
and the corresponding "ExtSign" script command.
RAR 3.0 archive format includes the end of archive marker,
so SFX module automatically stops extraction when reaching
the end of archive and all data appended to archive are
ignored by default;
g) if you specified INF file in SFX "Setup" command, SFX will
attempt to install it instead of opening its contents
in Notepad as in the previous version;
h) the new DOS SFX module is 32-bit, so it is not limited to 64 KB
dictionary more and can unpack any RAR 3.0 archives regardless
of dictionary size;
i) "SFX options" button in the archiving dialog opens directly
"Advanced SFX options" without intermediate selection of
SFX module. If you need to change SFX type, use "Module"
page in the advanced SFX options.
Please note that new SFX modules are able to unpack only RAR 3.0
archives. They must not be used with archives created by older
RAR versions.
