WinRAR 4

WinRAR 4 features

  1. RAR decompression speed is improved. Depending on data type,   decompression can be up to 30% faster than in previous versions.    Both the general RAR algorithm and most of special RAR multimedia methods benefit from this improvement. The only module of RAR
        algorithm, which is not affected, is "Text compression" method.
  2. Changes in ISO support:
    a) UDF support is upgraded to UDF 2.50 revision. It makes possible  to unpack most of Blu-ray ISO files;

      b) when browsing UDF ISO file, UDF revision number is displayed after the "UDF" format name in WinRAR address bar  and in archive information dialog;

    c) WinRAR sets the folder modification date when unpacking folders stored in UDF and ISO9660 files.

3.  Changes in password dialog:

        a) WinRAR uses the same format of password dialog both when archiving
           and extracting, so "Show password" option is available also
           when extracting;

        b) "Organize passwords…" button in password dialog provides
           access to password organizer interface, where you can specify
           your frequently used passwords. You will be able to access these
           saved passwords using the drop down list or autocomplete feature
           in password dialog.

           It is important to know that saved passwords are not encrypted
           and anybody having access to your computer can view them.
           Use "Organize passwords" feature only if your computer is
           protected from unauthorized access;

        c) "Use for all archives" option is available in password dialog
           when unpacking several archives at once. You can utilize it
           to apply an entered password to all archives.

           If you use this option with an empty password, WinRAR will skip
           all encrypted archives;

        d) Unlike previous versions, the password from default compression
           profile is not used for extraction.
           If you wish to use the same password for all extracting archives,
           press "Organize passwords…" button in the password dialog
           and define a new password entry, specifying "*" file mask
           in "Select for archives" field.
    4. In Windows 7 WinRAR will display the total operation progress
        also on WinRAR icon on Windows taskbar. You can disable it using
        "Taskbar progress bar" option on "General" page of WinRAR settings.

    5. Numerous Unicode support improvements allow to process non-English
        file names more smoothly. These improvements include:

        a) better Unicode handling in WinRAR in "Rename", "Convert",
           "Find" and other commands, in folder tree panel, in password
           request dialog and in many other parts of WinRAR interface;

        b) correctly displayed Unicode names in WinRAR items in Explorer
           context menus;

        c) Unicode support in .lng files, making WinRAR localization
           possible for Unicode only languages.
    6. Changes in -x<file> switch syntax. Now you can specify a wildcard
        exclusion mask for folders. Such mask must have the trailing ‘\’
        character, like -x*tmp*\ or -x*\temp\

    7. New "Extract relative paths" option in "Advanced" part of extraction
        dialog. If you browse some archive subfolder in WinRAR shell
        and enable "Extract relative paths" option, the path part up to
        and including the current subfolder will be removed from extracted
        file paths.
        For example, if you are inside of "Backup\MyData" archive folder
        and extract "Images" folder, it will be extracted as "Images",
        not as "Backup\MyData\Images".

        This option is the new default extraction mode, but you can change
        the default back to WinRAR 3.x style. Just select "Extract full paths"
        and then press "Save settings" in "General" part of extraction dialog.
    8. If TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links
        and if destination file system is NTFS, WinRAR will create these
        links when unpacking such archive. WinRAR will create symbolic links
        as symbolic and hard links as hard in Windows Vista and newer
        and it will create all links as hard in older Windows.

        If destination file system is FAT32 or any other not supporting
        file links, WinRAR will skip links when unpacking TAR, TAR.GZ
        and TAR.BZ2 archives.
    9. Recovery volume processing involves less disk seek operations
        resulting in higher performance.

    10. You can select Windows 7 library in tree panel in extraction dialog
        and WinRAR will use its default save location as the destination path.

    11. "Report" command allows to select HTML, Unicode text and usual text
        as output format for report file. Unlike previous WinRAR versions,
        now WinRAR preservers Unicode characters in reports when using HTML
        or Unicode text format. So non-English characters in file names
        will be displayed properly in such reports.
    12. Message list in GUI SFX archives displays only operation status
        and error messages. It does not contain names of all extracted files
        anymore. This change improves the speed and reduces memory requirements
        for SFX archives containing a large number of files. Also it makes
        easier to locate error messages, because they are not hidden among
        extracted file names.

    13. GUI SFX archives display "Extract" button instead of "Install"
        if no "Setup" or "Presetup" commands are present in the archive
        comment. If you prefer "Install" button, but do not need to
        execute any setup programs, you can add "Setup=<>" command.

    14. WinRAR displays the current percent above the operation progress bar
        when repairing an archive containing the recovery record
        and when processing recovery volumes.

    15. WinRAR limits the maximum possible volume size to 4 GB minus 1 byte
        when creating RAR volumes on a disk with FAT or FAT32 file system
        in volume size autodetecting mode. These file systems do not support
        4 GB and larger files.

    16. If "Wait if other WinRAR copies are active" option is enabled
        and WinRAR waits for another copy, you can press "Continue" button
        in command progress window to force WinRAR to stop waiting.
        So now "Continue" button allows to override the state of
        "Wait if other WinRAR copies are active" option for current operation.

    17. WinRAR displays one password request instead of two, when saving
        an encrypted file back to RAR or ZIP archive after modifying it
        in some external editor. Previous WinRAR versions usually requested
        the password twice, both when extracting the original file
        and archiving its modified copy. Only RAR archives with encrypted
        file names were processed with the single password prompt.

    18. New error code 10 ("no files") is added to list of error codes
        returned in command line mode by RAR and WinRAR. This new code
        can be returned by archive, extract, delete and repair commands.
        It means that RAR did not find any files matched the specified
        file or archive mask.

    19. File name area in file overwrite dialog occupies several lines now.
        It makes possible to display much longer names.

    20. Now switch -ep3 converts not only disk letters, but also UNC paths.
        So \\server\share will be converted to __server\share when archiving
        and restored to the original \\server\share when extracting with -ep3.

    21. New "Background extraction" option in "Advanced" part of extraction
        dialog places WinRAR into background, when extracting files.
        You can save its default state with "Save settings" button in "General"
        part of extraction dialog, just like for other extraction options.

        "Background archiving" option from the default compression profile
        does not affect the extraction behavior anymore.

    22. "Mode…" button in operation progress window is enabled also
        when extracting or testing archives. It provides access to
        "Command parameters" dialog, where you can set "Turn PC off when done"
        option for extraction and test operations.

        Previously this dialog was accessible only when archiving.
