Whats new in Version 5.20

   1. If Windows User Account Control prevents extracting or archiving
      commands to create files in system protected folders, WinRAR attempts
      to start its another copy with administrator privileges to complete
      the operation. It is necessary to confirm privileges elevation
      in response to User Account Control prompt to allow such second
      WinRAR copy to run.

   2. You can drag files in Explorer with right mouse button, drop them
      to some folder and select WinRAR archiving commands in context menu
      to create an archive with these files in the destination folder.

   3. It is possible to use WinRAR.ini file instead of Registry to store
      WinRAR settings. You may prefer such approach if you plan to install
      WinRAR to removable media, such as USB flash drive, and then run it
      on different computers.

      See "WinRAR.ini file" topic in "Configuration settings" chapter
      of WinRAR help for details.

   4. Added extraction support for ZIP and ZIPX archives using 
      XZ compression algorithm.

   5. If ZIP or ZIPX archive contains any compression algorithms except
      usual "Store" or "Deflate", algorithm names are displayed
      in "Version to extract" field of archive information dialog.
      Algorithms with names unknown to WinRAR will be assigned "m<num>"
      name, where "num" is a compression algorithm numeric identifier.

   6. "Open with WinRAR" command is available in Windows context menus
      for archive formats supported by WinRAR. It can be turned off
      with "Open with WinRAR (for usual archives)" option in WinRAR
      "Settings/Integration/Context menu items..." dialog.

   7. Command line RAR can read the default set of switches from rar.ini
      file stored in RAR program folder. Previously it was possible to
      define only the same set of switches for all RAR command with
      "switches=<switches>" string. Now rar.ini also allows to specify
      separate switch sets for individual RAR commands using
      the following syntax:

      switches_<command>=<any RAR switches, separated by spaces>

      For example:

      switches_a=-m5 -s
      switches_x=-o+

   8. Command "ch" supports switches -tl, -cu, -cl also for ZIP archives.
      Previously "ch" allowed these switches only for RAR archive format.

   9. For archive formats lacking file time information, such as .bz2,
      .xz and .Z, WinRAR sets container archive modification time
      to extracted files. It does not apply to tar.bz2, tar.xz and tar.Z,
      which use file time stored in tar headers.
   
  10. "Keep broken files" extraction option is supported for bzip2 archives.

  11. WinRAR icon in Windows context menus is scaled up correctly
      in high DPI screen modes such as 150% or 200% of normal text size.

  12. It is possible to disable WinRAR "Benchmark" command with
      "Benchmark" variable of HKEY_CURRENT_USERSoftwareWinRARPolicy
      Registry key. In multi-user environment "Benchmark" command might
      abuse shared computational resources. See "Registry variables" topic
      in "Configuration settings" chapter of WinRAR help for more details.

  13. Additionally to "sfxcmd" variable containing the entire command line,
      SFX module sets "sfxpar" variable containing command line parameters
      only, without leading SFX module name. These variables are set before
      starting a program specified in "Setup" command.

  14. File overwrite prompt in console RAR displays the size and modification
      time for existing and new files.

  15. When archiving from stdin with -si switch, RAR sets the current system
      time to modification time of archived file. Previous version did not
      set this time at all.

  16. It is possible to use -si and -v<size> switches together. Previous
      versions did not allow to create volumes when archiving from stdin.

  17. Warning is issued when starting unpacking 4 GB or larger file
      from RAR or ZIP archive to FAT32 patition, so user may cancel
      the operation. FAT32 does not support files of such size.

      Also this warning is issued when starting to create RAR archive
      with "Store" (-m0) method if estimated archive size is 4 GB or more.

  18. "Select all" button in "Settings/Integration" dialog is renamed to
      "Toggle all". Now it deselects archive formats if all they are
      already selected.

  19. "Delete archive" extraction option correctly removes all .zip and .7z
      volumes. Previously it removed only the first volume in the set
      for these archive formats
