7-Zip 15.00 Alpha x32 & x64 [Latest]

7-Zip 15.00 alpha

This is a development version.
Don't use this alpha version to process important files and archives.
The code of this version contains big number of changes.
And probably there are some new BUGs.
If you use 7-Zip 15.00 alpha, check 7-Zip's forum periodically for updated information.
If you need more stable version, you can use previous version: 7-Zip 9.38 beta.


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 BUG was fixed:
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
