I found exactly what you were looking for back in the days. Hope you are still interested in it. Check out this guy's Intelligent ZIP Archiver. Struggling to send multiple independent zip files within email limits (e.g., 18 MB)? No worries-feel free to use Yova's ZIP Archiver. It features intelligent file grouping and optional split volumes. Users can skip oversized files, preserve folder paths, and manage archiving efficiently through an intuitive drag-and-drop interface. https://youtu.be/Qg7cAxRU7PA?si=55W75EuDCzIefg7K...

@ipavlov There seem to be more PKG files publicly available now using PBZX also from other vendors besides Apple, e.g. https://statics.teams.cdn.office.net/production-osx/26059.604.4471.2584/MicrosoftTeams.pkg The link is from the HomeBrew formula JSON for Microsoft Teams and the path to the PBZX inside is MicrosoftTeams_app.pkg\Payload\Payload~ It's detected as LZMA2:23 by 7zFM.exe but opening it fails with the error "There are some data after the end of the payload data : Payload~". I would also...

Requesting for Hash value for LZMA SDK
-
Can 7zip provide a hash value to the file that I downloaded from the link below? https://www.7-zip.org/a/lzma2600.7z It is required for our security and compliance to validate the authenticity of a file before bringing it into our system, and when I try to verify it, it detects that the file is not signed and requires a hash value from the vendor. Any help would be appreciated

It's not what I envisioned with my GUI, but congrats on actually getting it implemented. Just like 99% of all my other projects, my 7z GUI failed at the implementation step due to life getting in the way because it is a little more than a weekend project for me…
-
7-zip.com is my official mirror of 7-zip.org. So it's safe to use 7-zip.com. But do not use the domain "7zip dot com" (domain name without the hyphen), because the domain "7zip dot com" is controlled by squatters.

As a workaround now you may use in console -scc switch like these: 7z.exe a -mx9 -sccutf-8 -mhe+ -psome_chinese_pass 1.7z dir/ And in GUI in parameters field apply: sccutf-8 Currently 7-Zip does not seem to recognize CP936 character encoding/codepage. And I don't know if it should as thee is UTF-8 to support all languages and even more signs, like emojis. There is another issue: people who don't know Asian languages don't even know how to input signs nor they know which sign. You would have to send...

Hello, Igor Pavlov! I'd like to clarify whether 7-zip.com is your official resource? I'm seeing threat alerts on VirusTotal, and I also came across a Malwarebytes article about fake installers. Could you please tell me if I should take any security measures if I just visited this website, or is it enough to just close it? I also don’t remember where I downloaded 7-zip from a long time ago, how can I check?

GCC16 shows the warning, if we have 2 classes: CHandlerImgProgress and CLocalProgress. If we have only one class, there was no error. If we add some dummy variables to one of these classes, it also work. So I think that it's bug in GCC16.

In case anyone is looking for a GUI for 7-Zip for Linux, you can use 7z-GUI-Linux (I built it). It has pretty much all the features that one would expect. It requires 7z installed on the system as a dependency, but other than that, there are no dependencies. I hope it helps someone. Cheers.

Dear 7-Zip developers and community, I would like to suggest a feature enhancement for 7-Zip. Feature Request Add an option to select the character encoding/codepage for password input when extracting password-protected archives. Problem Description Currently, when extracting an archive that was created with a password containing non-ASCII characters (e.g., Chinese, Japanese, Korean, or other non-English characters), 7-Zip often reports "wrong password" even though the password is correct. This occurs...

Thank you for your time spent

Now I don't think that we need terse support in 7-zip. Rare methods are useless.

I also can provide PCTERSE (windows) source code. This code was published but not supported yet. An existing PCTERSE binary code does not work under Windows 10/11

Maybe there is `static' somewhere in command line and it interferes with shared linking of shared object. At least that's what can be deducted from web search of relocation R_X86_64_32 against hidden symbol `TMC_END' can not be used when making a shared object.
-
OK, no need for xargs, some examples: find . -mindepth 1 -maxdepth 1 -type f -exec 7zz a -mx0 a.zip {} + 7zz x -so 7z2501-linux-x64.tar.xz | 7zz x -si -ttar | 7zz a -mx9 a.7z

7z/lzma2 now is faster than 7z/deflate, because 7-Zip can use multithreading for LZMA2. bzip2 is another algorithm - BWT. LZMA and deflate are both LZ algorithms. original idea was that 7-Zip supports all main algorithms in 7z format: LZ (LZMA), BWT(BZip2) and PPM (PPMd). BTW, you can enable Deflate by typing method in Parameters field for 7z archive: m=deflate
-
It's true, but only for compression ratio. Deflate is faster with compression and especially decompression, and that's exactly a reason why one would use it. If you expose bzip2 and, especially, ppmd, then you can equally well add deflate. Users who choose anything else than lzma know what they do, and will appreciate it.
-
The Deflate method doesn't show significant advantage over LZMA.
-
Why there is no deflate compression in 7z file manager for .7z format? It is natively supported in .zip and, de facto, natively in 7z.dll but it cannot be chosen in file manager for .7z format.
