I'm packaging 7-zip to a Linux distro. I'm not sure if I missed anything, but it seems that we can't create a DEBUG build unless hacking the makefile. I also see a few similar requests in Sourceforge.

May I open a PR to add an env flag here? like:

CFLAGS_BASE = ... 
ifdef DEBUG_BUILD
CFLAGS_BASE += -g
endif

By default, this change won't make any difference.

Is your feature request related to a problem? Please describe.

Dragging and dropping archives from 7-Zip to the temporary folder used by Explorer cannot be changed, always using environment variable %temp%.

On Linux 7z echoes password prompts.

Expected behavior is to either hide the input completely or replace all characters with '*'.

I've run a benchmark on Ubuntu 24.04 with a packaged version (GCC 13.2.0: SSE2) and a version from https://www.7-zip.org/download.html (GCC 9.4.0: SSE2). The former:

Почему на чтение открывает все wim файлы, а на изменение\удаление содержимого далеко не все. (от вида сжатия не зависит)

Часто пишет "Some files have incorrect reference count" и изменить ничего не даёт.

Вам известны "правильные" параметры в командной строке dism, для того чтобы создать wim который 7zip сможет открыть для изменения? Или это от версии dism зависит?

Hello,

I've recently built a project that relies on downloading 7za.exe on the fly to automate extracting an archive. 7zr.exe is not up to the task for this particular archive. As far as I know, 7za.exe is only officially available within the extra.7z package, which unfortunately requires 7-Zip to unpack. As a result, I've resorted to hosting 7za.exe alongside my own project-- but I'd prefer to link to an official release instead.

Is this a possibility?

Thanks!

On Linux, files in 7z archives packed from STDIN have attributes at all.

Expected behavior is to have default attributes: 775 | rwxrwxr-x

Hello. I have downloaded an old version of Windows 1.03 from Winworld for the HP 150 x86 based PC, and the disk images are all Teledisk image format (.td0). I do not have the ability to use Teledisk, as it is a DOS program, and I am running 64-bit Windows 7. Can you add Teledisk extraction support, as all the software I have for disk images, including 7-Zip cannot open them. Thanks in advance!

The winrar (?) had option if are selected several archives, and with right mouse button has menu - unzip each in different folder, where name of the folder is the name of the archive.
This is very convenient.

Is your feature request related to a problem? Please describe.

7-Zip Doesn't have auto update since it says offline. However, using third party such as Glary Utilities should work by detecting latest version.

What you want

I would like 7-Zip to have support check updates, including automatic and manual.

Describe alternatives you've considered

One of the alternate does have other programs have check updates such as gBurner, AnyBurn, ImgBurn, etc.

Additional Information

Per following this: https://sourceforge.net/p/sevenzip/discussion/45797/thread/c2066626d9/

Have you checked that no similar feature request(s) exist?

• I have searched and didn't find any similar feature request.

Hi, I could swear 7-zip had option to create MD5 hash of a file through the CRC SHA, but now I can't seem to find a way to do it, only CRC or SHA. Am I misremembering? If not, would it be possible to bring this feature back?

Is your feature request related to a problem? Please describe.

7-Zip does have English language for default. However, for some reasons, most of the words are using American text because English (United Kingdom) language is not present.

What you want

I would like to add English (United Kingdom) Language for 7-Zip. Because the flag is literally United Kingdom, and most words are different, such as Favoruites. as the American text is Favorites (in case on the menu bar).

Describe alternatives you've considered

Possibly, English (English) is the default language. The reason there are various region language for English regions such as United Kingdom.

Additional Information

Per following this: https://sourceforge.net/p/sevenzip/feature-requests/1600/

I also made English UK Flag with Logo, the logo is credited to the Nurudin.

Additional Context

Igor said he doesn't want add anymore languages, He asked about British English localization for Windows. To be honest, British English was introduced in Windows 8 for the main language since in 2012. that being said, the Language code is called en-GB.

I Initially make base for en.ttt file, then I save the text file for en-GB language. As soon I always update some strings, I always keep updated to make up to date in the future.

Comparing from ImgBurn, I initially made change several strings to matching from ImgBurn and some resembles from Windows 8. through 11. for example, "Computer" text would be "This PC", this will be resembled from Windows 8.1 through 11.

You can clearly see on the changes I made on the above, those are updated to keep my language file for British English.

In other words, some language flag are also appeared in various games such as FIFA 14 and FIFA 23, and other European games that including Language selection, these are flag named it: English (United Kingdom), or British English instead.

Here's what the language flag would looks like in FIFA 23:

If you see these, this means it's British English flag, so let me know if you interested this.

Please fix the 7-Zip installers so they clean up and don't add duplicates to Programs and Features:

Behaviour replication
Step 1
Enable 2 Panel View
Step 2
Close 7zip
Step 3
Open Zip File
Close 7zip
Open Different zip File

Resume:
Double click on zip file to open, the ZipFile is show on random panel (Left or right)
These makes quite confusing

Suggestion: when Open Zip File the same panel should be used ex: Left Panel

System information:
OS: Windows 10 22H2
7-Zip version: 24.05 x64

I have a 4K monitor and use 200% scaling and I have an issue with the context menu icons not scaling properly. I know that Windows has high dpi compatibility settings, and those work well with the 7-Zip GUI; however, they do not affect the context menu icons.

The 7-Zip icons are about half the size as the other context menu items as shown below:

Instead of using the bmp in 7-zip.dll for the context menu icon, could the ico be used instead, since there is both a 16x16 and 32x32 version?

Given that since (quite enough) many years already (source: Wikipedia) SHA-1 hash algorithm is practically being discontinued more and more, even if still quite widely used, my suggestion for next v24.05 or successive v24.06 beta is also to start lowering its importance by also changing displayed order for available CRC SHA hash calculation in 7-Zip shell integration context menu from SHA-1, SHA-256 to SHA-256, SHA-1 (as well as in 7-Zip own internal File -> CRC menu).
So here's a quick visual example of how actual CRC SHA menu appears displayed in Explorer after 7-Zip shell context menu integration (just like also displayed by 7-Zip internal File -> CRC menu) and how it would become after implementing my suggestion :

          CRC32                     CRC32
          CRC64                     CRC64
CRC SHA - SHA-1           CRC SHA - SHA-256
          SHA-256                   SHA-1
          ...                       ...

P.S. I've also already noticed and appreciated ( 👍 ) the fact that when choosing '*' in CRC menus (after 7-Zip Explorer shell integration and even in its internal one) SHA-256 calculation is already made and listed before SHA-1 one.

Could you put the program logo in the context menu?

can you update the software so on windows 11 context menu it shows before the show more options

For 23.01, -Werror triggered a lot of compilation errors when using Clang/LLVM 17 to build Alone2 on Linux.

I've confirmed that removing this specific option when using Clang can resolve the issue.

May I open a PR for this? The fix may be as follows.

ifneq ($(CC), xlc)
CFLAGS_WARN_WALL = -Wall -Wextra
ifndef USE_CLANG
CFLAGS_WARN_WALL += -Werror
endif
endif 

is there by any change to be added .zst format ?

Please add support to add/remove files/folders in IMG (FDD, HDD) and ISO files.

Describe the bug
If you try open notepad (such as Windows Notepad) running on Windows 2000 through Windows 7, the line ending is incorrect for Language text files.

To Reproduce

Steps to reproduce behavior:

1. Open the directory following these: C:\Program Files\7-Zip
   1.1: If you are running 64-bit but with 32-bit installed, find here: C:\Program Files (x86)\7-zip
2. Double click the Lang folder.
3. Click the text files anything you want, such as fr.txt and de.txt
4. See the line ending that is incorrect.

Expected behavior
Line Ending must set DOS/Windows that allowing CR and LF (according on MousePad xfce)

Screenshots
Here is the comparison Before and After.

The Before shows Unix Line Ending which there are lots of square symbol, meaning it is glitched if you run Windows Notepad. In Windows 10 v1809, it only works fine.

The after: This is the Line ending that I changed from Unix to DOS/Windows itself.

What version(s) of 7-Zip have this bug?
24.01 Beta x86 according below in environment and others.

Environment and others (please complete the following information)

• 7-Zip version: 24.01 Beta x86
• Operating System in Host OS: Windows 7 Ultimate 32-bit
• Guest OS (in Virtual PC): Windows XP

Additional Context
Line Ending for translation might glitched if you save again when you running on Windows, resulting error message appears (well, sort of). However, the issue was found back in version 24.01 released. In that circumstance, 23.01 is okay, since the Line ending had DOS/Windows itself.

However, the solution is simple, you can use Notepad2 by following select: File -> Line Endings -> Windows (CR+LF).
For Notepad++, there is line ending option called EOL Conversion.

I cant remove it

some websites use the same password for their zip files and the option to save them in maybe some kind of list would be a good QOL, as an example the password for their files are "ABCD.EFG" when the extractor asks for the password it can pre fill ( like browser search fields) or show the option when you press "A" to make it faster for the user to complete it. while it can be a security issue if not careful i feel it can be done as long as the person needs to intentionally in the setting page with maybe a small warning about the possible scenario.

thanks for the great app as well

Hello can you implement any of the following abilities?

-Update files based on file size and/or file modified time.
-Configure extract mode via config.
-Configure target directory via config. (In my test implementation I fallback to tempDir if extractPath not specified)
-Allow one to issue ShellExecuteEx /w runas verb via config so we can get elevation.
-ExpandEnvironmentStrings for paths in the config.
-Unicode by default.

Thanks!

btw in ReadDataString:
if (posTotal > (1 << 20)) return (stringResult.IsEmpty()); should be...
if (posTotal > (1 << 22)) return (stringResult.IsEmpty()); to handle reading config up to 4MB stub

There are many Simplified Chinese translations in the new version that have not been translated, which I have updated and supplemented based on the original translation.

Пожалуйста, получите доступ к машине на архитектуре Эльбрус (e2k) и исправьте ошибки сборки, которые появились в версии 23.

Всё из-за того, что вы добавили использование векторных интринсиков для Интела. Разработчики Эльбруса сделали конвертацию Интловских интринсиков в свои. У них есть поддержка всего до AVX2, но всё что выше SSE4.1 (включая AVX2, AES, SHA , что почему-то включаются по умолчанию) вы использовать не должны, потому что 256-бит векторов у Эльбруса нет, а интринсики для AES и SHA медленно эмулируются, так как на них нет эквивалентных инструкций.

Я сделал некрасивый патч, которым заткнул проблемы.

How to reproduce:

1. Create archive with 7z a archive-path.7z -mx=9 dir-to-archive
2. Wait till it will be properly archived
3. Try to verify integrity of archive with 7z t archieve.7z
4. Accidentally type Ctrl-C in terminal terminating the process of verifying.
5. Receive information about archive being corrupted and be sad.
6. Mind that you terminated the process and try again with 7z t archive.7z till it properly ends saying everything is ok. Be a little be confused.

Reproduced with 7-Zip 24.07 (x64) on Windows 11

What could be changed so, error message would state something like
Integrity check was interrupted by signal, proper information is not available?

Should it be done in a first place, because it already writes Break signaled with the last line of message after typing ctrl-c ?

the convention for source tarballs is that they extract to a directory with the same name as the tarball, without the tar.whatever extension:

zlib-1.2.3.tar.gz -> zlib-1.2.3

so 7z2407-src.tar.xz should extract to 7z2407-src

in my distro are 1467 packages, and only 7zip and 3 others are misbehaving in this regard.

Hi i See that only 29 lines is missing to translate. Where can I find localisation file/s to translate? Thanx.

So, i will like to get info about zip

• Extract to Folder

I have a suggestion for optimization on the tool panel of 7zip, to add a graphical element that implements one-click decompression (the function being to decompress to the current path). The purpose of this suggestion is to reduce the user's path selection operation and optimize the user experience.

eg.

I hope it will be adopted, thank you very much.

I used to be a winrar user, and that is the only feature that I miss every time I need to go trough lots of folders
