- File Protect: This feature allows you to protect your archives using password encryption. Only authorised users can view the content. This feature is particularly useful when working with sensitive data that needs to be further protected.
- Splitting Archive: You can use the app to split large archives up into smaller pieces, making them easier to store or transfer on multiple storage devices. This feature is useful when there are file size limitations or you want to distribute files on multiple media.
- Integration: It is integrated seamlessly into the Windows shell and allows users to access its functionalities via context menus. This integration simplifies the extraction and archiving process by providing easy and quick access to WinRAR features.
Pros | Cons |
Compression algorithms that are robust and efficient for reducing file sizes. File formats that are supported for both extraction and compression. Integrate with Windows Shell for seamless access to all features. Secure archiving with password encryption. Split large archives into smaller pieces for easier transfer or storage. | There is no option to recover passwords for archives that are protected. The interface design could use a modern update. |
What’s New?
- For RAR archives, compression dictionary sizes greater than 1 GB can be used. The amount of memory available can determine the size of the dictionary.
- For dictionaries larger than 4 GB, the power of two dictionary sizes cannot be specified. We are not restricted to the 4, 8, 16, 32, and 64 series but can also use values such as 5 GB or even 22 GB.
- Only WinRAR version 7.0 and newer can unpack archives with dictionaries larger than 4 GB. Unpacking archives containing dictionaries larger than 1 GB requires 64-bit WinRAR.
- WinRAR issues a prompt allowing you to cancel or continue if the dictionary size in the extracted RAR archive exceeds the “Maximum dictionary size allowed to extract” parameter in “Settings/Compression.” This is to avoid unexpected memory allocation.
- WinRAR’s default command-line mode does not allow archives to be unpacked if the dictionary exceeds 4 GB. Use -md and -mdx if you want to unpack dictionaries that are up to the specified size. Unlike -md, -mdx only applies to extraction and can be added as an environment variable to RAR. It does not affect archiving commands.
- The “Define dictionary sizes” dialogueue in “Settings/Compression” can be used to customise dictionary sizes proposed in the drop-down list associated with the “Dictionary size” field in the “Archive name and parameters” dialogueue.
- When creating RAR archives, you can use an alternative search algorithm that is optimised to find longer and more repeated data blocks. It can improve compression ratios and speed when dealing with redundant data, such as large text files.
- It can reduce compression speed and increase memory usage for certain types of data. WinRAR will apply the long-range search based on other parameters, such as the compression method and dictionary size, if the “Auto” option has been selected.
- The algorithm must be enabled for dictionaries larger than 4 GB.
- The “Exhaustive Search” option under the “Advanced compression parameter” dialogue or the -mcx command can be used to enable a much slower and more exhaustive search for repeated data and compression gorithms. This may provide additional compression for certain types of redundant data, but at a much slower compression speed.
- This mode is only effective if you use the extensive search option.
- The compatibility of archives created with exhaustive and long-range search options is not affected. If the dictionary size falls within the 128KB to 4GB range, then archives created using these search options will be compatible with all WinRAR versions starting from 5.0.
- The maximum path length has been increased from 2047 characters to 65535.
- The creation of archives in RAR format 4.x is no longer supported. The format-specific options and switches have been removed. This does not affect the RAR 4.x archive decompression that is already included in WinRAR.
- The “Propagate Mark of the Web” option is found in the “Settings/Security Dialogue” and controls the assignment of the archive mark of the b. You can choose to prevent propagating or allow it only for certain predefined groups of files, all files, or files matching a user-defined file mask.
- The mark of the web refers to the information that Internet browsers add when they download files. Different software can use it for security.
- Only GUI WinRAR supports this option. This option does not affect Console RAR’s ability to propagate Mark of Web.
- In “Settings/File List/Columns,” you can enable the “Attributes column”. The file attribute abbreviations are displayed; for example, ‘A’ is for “Archive” and ‘D” for directory.
- The numeric value is displayed if the file attribute is not recognized by WinRAR. This value is displayed in octal or hexadecimal for Unix attributes, depending on whether it’s Windows.
- The “Benchmark command” allows you to specify the exact thread count and copy results into the clipboard. The benchmark window includes information about WinRAR, Windows versions, and CPU and memory.
- The “Remove redundant folders from the extraction path” option is now available in “Settings/Paths.” This applies to both extraction commands initiated from the WinRAR interface and multiple archives unpacked into separate folders. The destination path is removed only if the name of that component matches both the name of the archive and its root archived folder, provided there are no additional folders or files within the archive root.
- If we unpack Pictures.rar, which contains the root folder “Pictures”, and then point the “Pictures’ destination to that folder, one of the “Pictures’ will be removed.
- It was only working for one archive that you selected from the context menu.
- The “Word Wrap in Comment” option under “Interface” in “Settings/General” toggles word wrapping mode in the archive comment window.
- The archive information dialogue now includes dictionary-size data for tar.gz, tar.bz2, and tar.lz.
- Switching -ol to OFF prevents the extraction and archiving of symbolic links.
- K bytes are assumed if the unit character is “b,” “B,” or not present.
- These switches only accepted bytes before.
- SFX TempMode accepts optional @set:user parameters to change temporary folder permissions so that only the current user has access. This prevents a user from replacing files in a temporary folder if SFX was started with another account.
- This can also be done with the “Restrict Folder Access” option found in “Advanced SFX Options/Modes.” Some installers may fail to launch in a directory created using the @set:user parameter.
- Hard link entries do not save file permissions or alternate streams. These are only saved for the file that these entries refer to. This allows for a reduction in archive size because the file properties are propagated automatically to hard link copies when extracted.
- The keyboard shortcuts such as Alt+E for unpacking found archives or Ctrl+A for selecting all files are now available in the “Search Results” window, even while the search is in progress. They were previously only available after the search was completed.
- Switch -v[unit] recognises ‘t” and ‘T” as terabytes or trillions of bits for volume size units.
- If the leading ‘-” character is missing from a parameter in WinRAR’s “Additional Switches” field, a warning is displayed. It is also issued when parameters in the RAR environment variables and rar.ini files lack a leading ‘-‘ character. Such parameters were previously ignored.
- The “Convert Archives” command shows the total operation progress. The total progress used to be updated abruptly when converting an archive and was only visible when processing multiple archives.
- Compressing the symbol link targets displays the progress correctly.
- “Integrate WinRAR into shell” option in WinRAR “Settings/Integration” is greyed out if “GlobalIntegration=0” is present in the winrar.ini file.
- By default, 64-bit WinRAR uses 64-bit SFX modules. Unpacking archives that contain dictionaries larger than 1 GB requires 64-bit SFX modules.
- The 32-bit modules have been renamed Default32.SFX, Zip32.SFX, and WinCon32.SFX.
- The maximum allowed dictionary size for archiving and extraction can be specified in gigabytes in the MaxDictA and MaxDictE variables in the “HKEY_CURRENT_USERSoftwareWinRARPolicy” registry key. These variables override WinRAR interface values if they are smaller.
- Console RAR removes the character 27 from the output. This is for security purposes, as this character could be used in terminal applications to declare ANSI Escape Control Sequences.
- Siddharth Dushantha brought this issue to our attention.
Fixed:
- It was possible to modify the security zone information of Mark of the Web using a specially designed.rar file. Orange Tsai, NiNi, and the DEVCORE Research Team at Trend Micro Zero-Day Initiative are to be credited with alerting us to this security flaw.
- Unrar.dll, unlike WinRAR, does not propagate the archive mark of the web. Instead, it leaves it up to the caller application whether to assign the archive mark to extracted files. Unrar.dll, therefore, is not affected by this problem.
- “User-defined archive extensions” field in “Settings/Integration” was not saved if Winrar Ini was used to store settings, and WinRAR was started under the non-administrator user account.
