    7-Zip 9.26 alpha was released.

    This is a development version.
    Din't use 7-Zip 9.26 alpha to process important files and archives.
    If you need more stable version, you can use 7-Zip 9.25 alpha.

    7-Zip for 32-bit Windows:


    7-Zip for 64-bit Windows x64:


    What's new after 7-Zip 9.25 alpha:

    - 7-Zip now can update WIM archives.
    - 7-Zip File Manager now can move files to archives.
    - The default encoding for TAR format now is UTF-8. You can use -mcp=1 switch for OEM encoding.
    - Command line version:
        - 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).
    - Speed optimizations for opening big archives and big disk folders.
    - Some bugs were fixed.
    - New localization: Aragonese.

    would you ever consider putting "Put each file/folder to separate archives" as an option on GUI?

    WinRAR has this option built into their GUI, but i prefer 7-Zip.
    Currently, im using command line/batches..

    and im also positive that this would make many Windows users happy!

    7-Zip 9.26 (x64 edition)
    Windows 7 Ultimate 6.1.7601 SP1 Build 7601
    During setup there is a 'Files in Use' message:
    'Windows Explorer (Process Id: 3064)
    If ignored, setup continues, no problem, except that the message has popped up.
    The only real bug that I saw quickly.
    Rightclick context menu doesn't show when a bunch of windows shortcuts ONLY, is selected.
    Maybe shortcut sizes are too small. When a different file is added, archive is created fine.
    Moving files works, for what I have tried.
    Something I noticed. Opened archive in archive, dropped 'aphoto.jpg' from windows into embedded archive, 'file copy' happens, but when going one level up after this, the embedded archive is not updated.
    Message is: 'The process cannot access the file, because it is being used by another process'.
    Could be improved upon, I guess…
    The first file dragged and dropped from an archive opened in 7zFM.exe into VLC-player, starts to play.
    More get error-messaqges, as usual in 7-Zip. However, some Players have this sort of drag-and-drop support.
    Winzip no, WinRAR yes. Would be a nice feature to add for 7-Zip as well.
    As would an option be, to enable archiving to LZMA2 by default, in the context menu.

    5 and 6 are not bugs either, I know.
