What's New:

  • 7-Zip File Manager now can operate with alternate file streams at NTFS volumes via "File / Alternate Streams" menu command.
  • 7-Zip now can extract .zipx (WinZip) archives that use xz compression.
  • new optional "section size" parameter for BCJ2 filter for compression ratio improving.
  • Example: -mf=BCJ2:d9M, if largest executable section in files is smaller than 9 MB.
  • Speed optimizations for BCJ2 filter and SHA-1 and SHA-256 calculation.
  • Console version now uses stderr stream for error messages.
  • Console version now shows names of processed files only in progress line by default.
  • new -bb[0-3] switch to set output log level. -bb1 shows names of processed files in log.
  • new -bs[o|e|p][0|1|2] switch to set stream for output messages;
  • o: output, e: error, p: progress line; 0: disable, 1: stdout, 2: stderr.
  • new -bt switch to show execution time statistics.
  • new -myx[0-9] switch to set level of file analysis.
  • new -mmtf- switch to set single thread mode for filters.

The BUG was fixed:

  • 7-Zip didn't restore NTFS permissions for folders during extracting from WIM archives.
  • The command line version: if the command "rn" (Rename) was called with more than one pair of paths, 7-Zip used only first rename pair.
  • Some bugs were fixed.
