    No, but such "relicts" can be later overlooked and lead to undesirable results.

    I did some further analysis of EN.TTT file. I fixed some language issues and corrected and extended shortcut keys.

    I hope it is ok to report bugs here. I couldn't find a more appropriate place.

    I tried to extract a multi-archive (or it is called multi-volume?) rar file, but it was bigger than my ram drive and I got the appropriate error message when it got full.
    After that I couldn't press the OK button, it was impossible. I also tried 9.22 beta but the same happened. Finally I found that pressing Escape would help.

    I think it would be nice if it checked for enough space before starting the decompression.

    How can I specify which checksum / hash I want for the 'h' flag ?
    If i want the full sha-256 to be calculated and dumped out say.

    Another small question:  the 7zFm can calculate the CRC's and SHA -256 through the File->Calculate Checksum.
    What is strange is why on that "Checksum information" window you cannot copy any of the info.
    Visually inspecing the SHA-256 is quite a pita.

    1) 7z h -mm=sha256 file.txt
    2) You can press Ctrl+Insert to copy text from GUI message box.

    I'm seeing alot of files w/ identical crc32 but different content in my archives. And automated methods of scanning them requires decompression and recalculating using different hash algorithms.

    Are there any way to save/store SHA-1 or SHA-256 of files within the 7z archive for use and not as a separate txt file? 

  • Igor Pavlov

    Igor Pavlov - 2011-11-21

    7z stores only crc32 now.

    Describe your tasks.
    Why do you need to find identical files?

  • szfong

    szfong - 2011-11-21

    I use a utility to scans zip files for duplicate files and whenever I'm looking for say, a Microsoft ISO from Technet or MSDN, the CRC32 is often 0xffffffff, which requires me to input the sha1 and each time it encounters such a file, a decompression needs to be performed.

    I also store alot of jpg, png, image files & some of them, although differ in size can have the same crc-32.  I use to be able to uniquely store them in archives and search thru them very quickly, but more and more of them are having the same crc-32.

    It would also be very convenient to have either sha1 or sha256 for use on virus/trojan scanning sites without having to decompress & recalculate the checksum hashes.

  • Igor Pavlov

    Igor Pavlov - 2011-11-22

    1) why do you scan ZIP for duplicate files?
    2) what ISO file in MSDN has 0xffffffff CRC?

  • Bulat Ziganshin

    Bulat Ziganshin - 2011-11-22

    > the CRC32 is often 0xffffffff,

    i recommend you to recompress such file to the new archive - pretty sure that crc will be different and ms use this vakue as "don't care" flag. another reason may be that this file is aes-encrypted and <20 bytes large - these files crcs aren't stored due to security reasons

  • Anonymous - 2011-11-23

    You can use the advapi32.dll/CryptCreateHash to calculate MD2/MD4/MD5/SHA1 hash (since Win95/Internet Explorer 3.0). That way, your program size will not increase while supporting more hash functions. It's very simple http://msdn.microsoft.com/en-us/library/windows/desktop/aa379908%28v=vs.85%29.aspx

    1 Упаковал папку установленного архиватора (7- zip) в 3 зашифрованных архива:
    7-Zip111.7z - формат 7z, архив зашифрован, заголовки зашифрованы
    7-Zip111h.7z - формат 7z, архив зашифрован, заголовки НЕ зашифрованы
    7-Zip111z.zip - формат zip, архив зашифрован
    2 Распаковываю их по ПКМ -> Распаковать в "7-Zip111\" : каждый архив в свою папку по имени архива
    3 После появления окна ввода пароля нажимаю кнопку "Отмена"
    4 Получаю:
    - папка 7-Zip111 не создается
    - папка 7-Zip111h создается, но она пуста
    - папка 7-Zip111z создается и имеет вложенную папку 7-Zip с единственным файлом 7-zip.chm нулевого размера

    Почему во втором и третьем случае вообще создаются эти папки ибо толку от них 0 ?
    Почему архиватор не удаляет их после нажатия на кнопку Отмена, что было бы вполне логично?

    7-Zip checks password only when it required.
    But it makes all things that doesn't required password.

    Maybe it's not good, I'll think about it later.

    From help file:
    "LZMA2 also supports all LZMA parameters, but lp+lc cannot be larger than 4."

    lp+lc affects memory consumptation and some other things. It was limited to lp+lc <=4 in LZMA2 to simplify decoder.
    So LZMA2 decoder (and XZ decoder ) is more robust than LZMA decoder.

    Simple bug, but I thought I mention it. When you open, for instance, a text file within the archive, the path (of the archive, plus possible directories within the archive) in the title bar disappears.
    I have WIndows 7, 64 bit.

    Strange behaviour in 7zFM:
    When holding CTRL-Key (e.g. for selecting multiple files) the text in the status bar starts to flicker.

  • Igor Pavlov

    Igor Pavlov - 2012-01-08

    I'll fix it. Thanks!

    Do you see it for any folder?

  • Ede_123

    Ede_123 - 2012-01-08

    Yes, I just tried different folders (including root folders / ntfs volumes / archives) and the flickering was present in all of them.

    It's visible best when selecting a file or folder: The different strings in the status bar flicker irregularly and apparently not at the same time. I wasn't able to determine any sort of regularity yet.

    Furthermore I noticed that CPU usage of the process 7zFM.exe increases slightly while holding the CTRL-key (from close to 0% to about 3-5% on my machine according to windows task manager).

    For the record: I'm using Windows 7 x86, Aero on, in case this has something to do with the problem.

    Hello, Igor.
    Could you add support for NTFS junctions and symbolic links? May be, through additional switch?

    Перетаскиваю на ярлык 7zFM.exe зашифрованный файл. Появляется окно распаковки с окном ввода пароля, но… На панели задач нет значка архиватора! Пароль не всегда под рукой и его часто приходится искать в истории аськи, почте или текстовом файле, где этот пароль сохранен. Для этого открываются дополнительные программы, окна и т.д…. После того как пароль найден, приходится искать окно ввода пароля,т.к., оно скрыто под множеством окон и не имеет значка на панели задач. Это не удобно.
    Можно ли сделать так, что бы значок на панели задач появлялся сразу же после появления окна ввода пароля?

    I don't provide source code for alpha versions of 7-Zip.
    Usually I release beta version with source code a few days after alpha version.
    But now I have too many unfinished changes in source code for next version.
    You can expect next version in April.
