Whats New

WinRAR - What's new in the latest version Version 3.70 beta 8 1. Bugs corrected: a) WinRAR shell extension did not work in Windows NT 4.0; b) when unpacking ZIP archives in command line mode WinRAR returned "write error" (numeric 5) code in situations when it should return "create error" (numeric 9). Version 3.70 beta 7 1. Bugs corrected: a) -ioff switch did not work in unrar.exe; b) WinRAR 3.70 beta failed to process volumes with malformed file name extensions like .rar, .002, .r03. It continued to ask for next volume even after specifying its exact name; c) WinRAR shell extension did not work in Windows 95. Version 3.70 beta 6 1. Bugs corrected: a) WinRAR shell did not allow to create recovery volumes for locked RAR volumes. Now the recovery volumes option is accessible for both locked and not locked RAR volumes; b) WinRAR displayed incorrect sizes for files inside of UDF ISO archives if file size exceeded 4 GB. Such files were unpacked correctly, but their sizes in file list window were displayed wrong. Version 3.70 beta 5 1. Bugs corrected: a) when unpacking TAR archives, WinRAR 3.70 beta versions truncated unpacked names by one character if length of unpacked file name was 100 characters or more; b) WinRAR 3.70 beta versions could fail to properly unpack RAR volumes if number of volumes exceeded 100 and volumes used the old style naming scheme. Version 3.70 beta 4

1. New "Request administrative access" option in "Advanced" page of "Advanced SFX options" allows to create SFX archive, which will request the administrative access when started in Windows Vista. Command line equivalent of this option is -iadm switch. 2. Correction in DBCS encoding (Japanese, Chinese, etc.) support in WinRAR shell extension for Windows 9x/Me. 3. Corrected a bug in extracting files from UDF ISO images exceeding 4 GB. Version 3.70 beta 3 1. It is possible to set the string value "AppData" in Registry key HKEY_CURRENT_USER\Software\WinRAR\Paths to override the default %appdata%\WinRAR path for WinRAR settings. For example, if you wish to store theme files in WinRAR folder, set this value to "c:\Program Files\WinRAR". 2. Total progress bar is displayed when unpacking UDF ISO files. 3. In previous versions archive icons were not changed when selecting a new WinRAR theme in Windows Vista. 4. WinRAR displays a warning if resulting archive is self-extracting and archive size exceeds 4 GB. Windows cannot run executables of such size. 5. Corrections in ISO processing code. Version 3.70 beta 2 1. Positions of "Mode" and "Cancel" buttons in archiving dialog have been exchanged. 2. Bugs corrected: a) beta 1 could truncate names of files decompressed from ISO 9660 archives by one character; b) progress bars in archive conversion window did not work correctly with "Windows progress bars" option turned on; c) "Load WinRAR settings from" dialog did not displayed if settings.reg was not present in %appdata%\WinRAR folder. Version 3.70 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; e) New "Request administrative access" option in "Advanced" page of "Advanced SFX options" allows to create SFX archive, which will request the administrative access when started in Windows Vista. Command line equivalent of this option is -iadm switch. 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<path> -p

set the destination path specify a password

-s -s1 -s2 -sp<par>

silent mode, hide all same as -s silent mode, hide start dialog 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. Version 3.62 1. Bugs fixed: a) stack overflow vulnerability has been corrected in WinRAR module processing 7-Zip archives;

b) WinRAR GZip module could set a wrong file date when unpacking GZip archives. Version 3.61 1. 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. 2. Resolved a compatibility issue preventing WinRAR 3.60 to run in Windows 95. Version 3.60 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<size> and -sm<size> 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.
