What's new after 7-Zip 9.07 beta:

- 7-Zip now can unpack Apple Partition Map (APM) disk images.
- Speed optimizations in AES code for Intel's 32nm CPUs.
- Speed optimizations in CRC calculation code for Intel's Atom CPUs.
- Some bugs were fixed.

<BR />
What's new after 7-Zip 9.08 alpha:

- VHD support was improved.
- Some bugs were fixed.

I cant believe it, on Win32.  The monster progress window with soccer field big empty area is still present…

Ok, no problem in alpha/beta, but this reminds me on some bugs in 7zFM from 4.xx. for years…

Tiny bug, not very dramatic, don't know if it's new or not, but will test with 9.07 too:

When testing several archives in a row, where you have among them a ".gz" archive over 4GB, the "processed:" filed gets updated, once testing of "gz" archive is over, with the incorrect size stored in the archive, rather then the actual size that resulted from the test. That way, everything looks OK during the testing of the archive, but once finnished, the "processed" size drops, and "Compression ratio" filed jumps to several hundred precent.

Please add an option to disable copy and folder history.

I once sent a patch that adds autocomplete support to the Extract files window. Someone replied me that 7zip doesn't run on Windows. Can you please add that feature? It's a one or two liner.

Hello everyone,

anyone willing to say "Thank you, Igor!"?
So let me start => Thank you, Igor! *thumbs-up*

Best regards!

> anyone willing to say "Thank you, Igor!" 

YES, I'll just test carefully first ;-)

Thanks are not required now.
So post bug reports.

For example, you can check latest VHD code.

- download Disk2vhd tool from microsoft.com
- create image of some drives (you can select small drives for speed).
- try to open that vhd with 7-Zip and then try to open NTFS / FAT files inside vhd. Note that MBR is open also by default when you open VHD.

with version 4.65 when i open cab sfx, i see directory structure.
with version 9.0x alpha/beta this dont work. try for example nvidia display drivers:  http://us.download.nvidia.com/Windows/195.62/195.62_desktop_winxp_32bit_english_whql.exe

>  Thanks are not required now. So post bug reports.

The 3 things (at least the attribute issue is IMHO a BUG) are still in with 9.09:

Hello everyone,

at Igor: true, but sometimes nice to have :-) But you are right => daily work has to be done either.

at pr0fessoro: this is by design. If you open the largest file inside the exe-file you will find the things you are looking for (hopefully ;-) ) Iirc this has been added by Igor to give possibility to view all included archives inside an exe-file. This does not occur on all exe-files (afaik only for installers).

Best regards!

Furthermore problems to open zip-archives:

The problem reported in:

https://sourceforge.net/projects/sevenzip/forums/forum/45797/topic/3482023

still exists in 9.09

Is it possible to procede installation without reboot at the and of process? WinRAR also integrates to Shell but doesn't ask to reboot my PC.

Thanks.

And of course, please, pay some attention to UI, please!

Please, provide 7za.dll both x86 and x64 version for testing with 3rd party apps.

You can download extra package with 7za.dll now.

Is it ok for you that 64-bit 7za.dll uses msvcrt.dll ?

> You can download extra package with 7za.dll now. Is it ok for you that 64-bit 7za.dll uses msvcrt.dll ?

Well, the msvcrt is almost installed everywhere so, please, provide the version that could use the better memory and/or disk footprint. ;)

Almost forgot, please provide the x64 version of 7zxa.dll too ;)

Igor, are there any x64 OSes that don't provide 64-bit msvcrt.dll?

As I understand first x64 versions were win2003 x64 and XP x64  (that is actually is same win2003 x64) and both these versions contain msvcrt.dll.

But maybe there are some another reasons why it's not good that 7za.dll x64 loads msvcrt.dll?

Windows 7 x64 contains msvcrt.dll (here, italian MSDN version)

Thank you for your continued effort on 7-zip, Igor. It is my preferred command line archiver.

I've seen other pre-existing feature requests in this thread mentioned and wanted to mention that I'm still hoping for a MOVE command to complement the ADD and UPDATE commands.

It is the only feature that I miss from decades of using pkzip!

There is no speedup from 4.65 to 9.09 (see shots above, 200 MHz CPU), also no compression improvement in LZMA algo.

There is also no compression improvement from 4.42 to 4.65 and no compression speedup either (exact results vary, may get very marginally better or very marginally worse).

There is a nice DECOMPRESSION speedup from 4.42 to 4.65 :-)
