This is a development version.
Don't use 7-Zip 9.30 alpha to process important files and archives.
If you need more stable version, you can use 7-Zip 9.25 alpha.
- The BUG in 7-Zip 9.26 alpha - 9.29 alpha versions was fixed.
These alpha versions could not open non-solid 7z archive, if
some files were skipped during creation of that archive.
That problem is also related to 7z archives created in solid mode,
if each solid block contains no more than one file.
Note: 7-Zip skips files that were open for writing by another
application and shows warning in that case.
What's new after 7-Zip 9.22 beta:
- LZMA2 now is default compression method for .7z format.
- LZMA decompression speed was improved.
- 7-Zip File Manager now can move files to archives.
- 7-Zip File Manager now can calculate CRC-32, SHA-1 and SHA-256 checksums for files.
- The default encoding for TAR format now is UTF-8. You can use -mcp=1 switch for OEM encoding.
- Speed optimizations for opening big archives and big disk folders.
- 7-Zip now can update WIM archives.
- DMG support was improved
- "compress and send to email" code was improved to support more email clients.
- Command line version:
- new command "h" to calculate hash values CRC-32, CRC-64, SHA-256 or SHA-1 for files on disk.
- new "rn" command to rename files in archive.
- new -sdel switch to delete files after including to archive.
- new -sns switch to store NTFS alternate streams (for WIM format only).
- new -sni switch to store NT security information for files (for WIM format only).
- new -stl switch to set archive timestamp from the most recently modified file.
- new -spf switch to store full file paths including drive letter to archive.
If you use -spf switch with extract command, please check that file names
in archive are correct.
- The format of language files was changed.
- Some bugs were fixed.
7-Zip 9.30 alpha version is provided without source code.
Source code will be released in future beta version.
Please write here about any new bugs.

Hello - I'm having an issue trying to install 7-zip on Windows 8 x64. I've tried all of the alphas, .22, .25, and .30, x64 installers and each time the installation just hangs. I've also tried running the msi as an admin (msiexec /a). Has anyone else run into issues trying to install 7-zip?

I have successfully installed version 9.22 x64 (.msi, at http://sourceforge.net/projects/sevenzip/files/7-Zip/9.22/7z922-x64.msi/download) on a Windows 8 x64. I had previously tried installing 7zip x32 (the .exe one) and did have some trouble. But not with the first one I suggested above. Of course, from the main Administrator account.

It is a setup installer (.exe) for Macrium Reflect. Using 7-Zip 9.20 I can view and extract all its contents, but using 7-Zip 9.30 alpha I can only view one file and extract that one file. Any extra information you need just ask me. I hope you can fix it.

Thank you for your answer! It worked, now I can view the files into 7-Zip. Is there a command line to instruct 7-Zip to extract the files this way as well? I ask that because using "7-Zip / Open Archive / *" I can view and extract the required files using 7-Zip GUI. But when I extract using 7-Zip context menu 7-Zip still extracts only the largest file inside exe as you have mentioned before.

Hello Pavel,
7zip version 9.30 is alpha version almost 10 months,
When do you plan to announce that 7zip version 9.30 as version that ready to move to producing environment and not alpha version?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Simple question: Will 7zip 7.30 reach final state some time in the near future?
If there's seen no need to develop the current alpha further, then why not announce it final and put it up on SF?
For the people complaining about things like missing context menu icons (wow): use PeaZip or something like that.

Yes, there is BUG in xz decoding code.
I'll fix that BUG in next version.
Thanks!!!
Can we get an official release and not a beta soon, please.
Dear Mr Pavlov,
I have been experiencing the following problem with this file:
http://download.cnet.com/Macrium-Reflect-Free/3000-2242_4-10845728.html?part=dl-&subj=dl&tag=button
It is a setup installer (.exe) for Macrium Reflect. Using 7-Zip 9.20 I can view and extract all its contents, but using 7-Zip 9.30 alpha I can only view one file and extract that one file. Any extra information you need just ask me. I hope you can fix it.
Best regards,
Aeolis
7-Zip opens largest file inside exe.
It works OK in most installers.
You still can open top level archive (EXE) via context menu:
7-Zip / Open Archive / *
Dear Mr Pavlov,
Thank you for your answer! It worked, now I can view the files into 7-Zip. Is there a command line to instruct 7-Zip to extract the files this way as well? I ask that because using "7-Zip / Open Archive / *" I can view and extract the required files using 7-Zip GUI. But when I extract using 7-Zip context menu 7-Zip still extracts only the largest file inside exe as you have mentioned before.

Dear Mr Pavlov,
Thank you very much!

As someone who does frequent archiving for version control, I think that this would be very useful:

Hi Mr Pavlov,
Do you have plans to continue supporting the IA64 architecture in future releases?
Thank you
It's not difficult for me to compile IA-64 version.
Probably I'll upload IA-64 version for next 7-Zip beta.
How do you use IA-64 version of 7-Zip?
Thank you Mr Pavlov. We have a few old Itanium 2 rack servers for specific in house aplications. Windows is rarely used on them but have a native version of your software is very appreciated!
So..I'm hoping for a Windows RT version for 7-zip. Will there be an ARM version for Windows in the future versions?

Hi! 7z don't support rar5's rar file
can 7z add support of it?
Hi,
The -spf switch error is still in 9.30 :(
7-Zip 9.30 alpha contains only the fix for that BUG with non-solid 7z archives.
I supposed that I had to fix that BUG as soon as possible.
Any other changes are in main code branch that is still under development.
Ok, I understand.
Meanwhile i find workaround for -spf switch bug. I make junctions (mklink command) to all my hard drivers and than with standard 7zip behaiour create archive :) I works in that same way as -spf switch (for my purposes).
Thank you for that quick bug-fix, Igor :).
Works like a charm :).
Kind regards,
