    WinRAR - What's new in the latest version

    Version 5.50

    1. WinRAR and command line RAR use RAR 5.0 archive format by default.
    You can change it to RAR 4.x compatible format with "RAR4" option
    in archiving dialog or -ma4 command line switch.

    If you prefer RAR 4.x format by default, use "Create default..."
    button on "Compression" page of WinRAR settings and set "RAR4"
    in the displayed dialog.

    This change affects only new clean installs. If you already saved
    RAR format in the default compression profile in previous versions,
    WinRAR respects stored settings.

    2. Use "Set master password" button in "Organize passwords" dialog
    to encrypt saved password records and protect them from unauthorized

    If saved passwords are protected with master password, you need to
    enter the master password and press "OK" in password prompt to access
    them. If entered password does not match the master password,
    it is treated as a usual password for archive operations.

    Once entered, the master password is valid until WinRAR is closed.
    Close WinRAR and open it again after specifying the master password
    if you wish to see how protection works. Enter a valid and then
    empty master password to remove encryption from previously protected
    password records.

    This WinRAR version uses a new data format for password organizer,
    so passwords stored in "Organize passwords" dialog are not readable
    by older versions. It does not affect archive encryption formats
    and encrypted archives are compatible with previous WinRAR version.
    Organizer data is converted to a new format only when you save it
    and not immediately after installing WinRAR.

    3. Prompt proposing to set the master password is displayed
    when storing a password in compression profile. You can enter
    the master password to encrypt password data stored in Registry
    and protect it from unauthorized access. You will need to enter
    the master password in password prompt dialog to access
    such compression profile after that.

    Once entered, the master password is valid until WinRAR is closed.
    Close WinRAR and open it again after specifying the master password
    if you wish to see how protection works.

    4. By default, WinRAR uses AES-256 in CTR mode to encrypt ZIP archives.
    While AES-256 is significantly more secure than ZIP 2.0 legacy
    encryption algorithm, it can be incompatible with some older
    unzip software. If compatibility with such tools is required,
    you can enable "ZIP legacy encryption" option in the password
    dialog or use -mezl switch in the command line mode.

    5. Added extraction support for .LZ archives created by Lzip compressor.

    6. Modern TAR tools can store high precision file times, lengthy
    file names and large file sizes in special PAX extended headers
    inside of TAR archive. Now WinRAR supports such PAX headers
    and uses them when extracting TAR archives.

    7. New "Store modification time" option on "Time" page of archiving
    dialog can be used to prohibit storing the file modification time
    in RAR 5.x archives. Former "High precision modification time"
    option is replaced by "High precision time format".

    8. New "Full paths in title bar" option in "Settings/General" dialog.
    If enabled, the full path of currently opened folder or archive
    is displayed in WinRAR title bar.

    9. New "File types to open as archives first" option
    in "Settings/Compression". Here you can define how Enter
    or double click on a file with non-archive extension and archive
    contents should be processed in WinRAR file list in file
    management mode. Examples of such files are .docx or self-extracting
    .exe archives. You can instruct WinRAR either to open such files
    as archives first or to execute or open them in associated programs.

    Default settings are to open self-extracting exe and to run
    other types of archives with non-archive extension.

    Regardless of these options, you can always open any such
    archive file by pressing Ctrl+PgDn on its name in WinRAR file list.

    Default folders for archives and extracted files are moved
    from "Settings/Compression" to "Settings/Paths".

    10. New "Copy full names to clipboard" command in "File" menu
    places full names of selected files to clipboard.

    11. Changes in the context menu displayed when right clicking
    the file list in WinRAR:

    a) several commands, which are also present on the toolbar
    or in main menu, such as "View" and "Repair", are removed
    from this context menu;

    b) "Copy full names to clipboard" command is added;

    c) "Run" for executables, "Open in associated application"
    for associated files and "Show archive contents" for archives
    are added. They allow to choose a way to process SFX archives
    and archive files with non-archive extensions.

    These items are present only in the file management mode
    and are not available inside of archives.

    12. LZ and ZIPX are added to list of associations in Settings/Integration

    13. LZ and ZIPX extensions are added to default list of formats for
    -ms switch ("Specify file types to store") invoked without parameters.

    14. You can specify 'f' charset value in -sc switch to use UTF-8
    encoding. For example:

    rar a -scfl arcname @filelist.txt

    to read contents of filelist.txt as UTF-8 text.

    15. RAR "lt" and "vt" commands display file times with nanosecond
    precision. Such precision is used in RAR5 archives created
    by RAR/Unix 5.50 and newer. Archives created by WinRAR have 100ns
    file time precision.

    16. Only '+', '-' and '1' precision modifiers are supported
    in -ts switch now. Use '+' to store the file time with maximum
    precision, '-' to omit the file time and '1' to store it with
    1 second precision. Intermediate precision modes previously
    defined with '2' and '3' modifiers are not available in RAR 5.0
    archive format and ignored by -ts switch.

    17. If a wrong password is entered when unpacking an encrypted file
    in RAR5 archive, WinRAR proposes to enter a valid password
    for same file again instead of aborting extraction.

    18. File path information is displayed if mouse pointer is placed over
    a name of archiving file in the operation progress window.

    19. Name of currently active compression profile is displayed
    in the archiving dialog above "Profiles..." button.

    20. If "Find" command is invoked from inside of archive subfolder,
    "File names to find" will include the path to this subfolder.
    So "Find" will search only starting from this subfolder.

    21. Bugs fixed:

    a) fixed crashes and security vulnerability when unpacking corrupt
    RAR archives;

    b) WinRAR failed to unpack files in ZIP archives compressed
    with XZ algorithm and encrypted with AES;

    c) if "Windows progress bars" option in WinRAR settings was turned off
    and "Put each file to separate archive" archiving mode was used,
    "gold" part of total progress bar did not display the compressed
    data ratio correctly;

    d) SFX archive extraction progress was incorrect in case of
    multivolume SFX archive with total volume size exceeding 4 GB;

    e) if archived folder name included trailing spaces, if user
    selected and extracted some folders in non-root archive folder
    and if "Allow potentially incompatible names" extraction option
    was turned off, WinRAR could lose one or more leading characters
    in extracted folder name;

    f) if only creation or only last access file time was stored in RAR5
    archive with 1 second precision, such as with -ma5 -tsm- -tsa1
    switches, this stored time was ignored when extracting.

    Version 5.40

    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

    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 <pwd> 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.
