大塔森林鉄道のインクライン跡と大塔支線

大塔森林鉄道は紀伊半島の山奥、和歌山県田辺市本宮町静川地区にあった森林鉄道です。
素掘りのトンネルやコンクリ橋桁等、随所に残る遺構群はインターネット上でもよく知られています。

今回は、インターネット上では知られざる?インクラインや「大塔支線」を探索しました。

7-zip32.dll/7-zip64.dll/7z.dll文字化け対策版 Ver.23.01.00.01公開

7-zip32.dll/7-zip64.dll/7z.dll文字化け対策版 Ver.23.01.00.01を公開しました。

○Ver.23.01.00.01 – 2023/7/2
・7-Zip 23.01をベースにビルド。
・一部ZIP書庫で文字化けする不具合を修正。(Special Thanks!:通りすがりの人様)

21.07から23.01の更新内容は下記のとおり。

23.01 2023-06-20

  • The page “Language” in 7-Zip’s menu Tools/Options now shows information
    about selected translation, including the number of translated lines.
  • Some bugs were fixed.

23.00 2023-05-07

  • 7-Zip now can use new ARM64 filter for compression to 7z and xz archives. ARM64 filter can increase compression ratio for data containing executable files compiled for ARM64 (AArch64) architecture. Also 7-Zip now parses executable files (that have exe and dll filename extensions) before compressing, and it selects appropriate filter for each parsed file:
    • BCJ or BCJ2 filter for x86 executable files,
    • ARM64 filter for ARM64 executable files.
      Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files.
  • Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB.
    It can increase compression ratio for executable files larger than 64 MiB.
  • UDF: support was improved.
  • cpio: support for hard links.
  • Some changes and optimizations in WIM creation code.
  • When new 7-Zip creates multivolume archive, 7-Zip keeps in open state
    only volumes that still can be changed. Previous versions kept all volumes
    in open state until the end of the archive creation.
  • 7-Zip for Linux and macOS now can reduce the number of simultaneously open files,
    when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid
    the failures for cases with big number of volumes, bacause there is a limitation
    for number of open files allowed for a single program in Linux and macOS.
  • There are optimizations in code for 7-Zip’s context menu in Explorer:
    the speed of preparing of the menu showing was improved for cases when big number of
    files were selected by external program for context menu that contains 7-Zip menu commands.
  • There are changes in code for the drag-and-drop operations to and from 7-Zip File Manager.
    And the drag-and-drop operation with right button of mouse now is supported for some cases.
  • The bugs were fixed:
  • ZIP archives: if multithreaded zip compression was performed with more than one
    file to stdout stream (-so switch), 7-zip didn’t write “data descriptor” for some files.
  • ext4 archives: 7-Zip couldn’t correctly extract symbolic link to directory from ext4 archives.
  • HFS and APFS archives: 7-Zip incorrectly decoded uncompressed blocks (64 KiB) in compressed forks.
  • Some another bugs were fixed.

22.01 2022-07-15

  • UDF support was improved to UDF version 2.60.
  • HFS and APFS support was improved.

22.00 2022-06-15

  • 7-Zip now can extract APFS (Apple File System) images that can be used in DMG files.
  • 7-Zip now can create TAR archives in POSIX (pax) tar format with the switches
    -ttar -mm=pax or -ttar -mm=posix
  • 7-Zip now can store additional file timestamps with high precision (1 ns in Linux)
    in tar/pax archives with the following switches:
    -ttar -mm=pax -mtp=3 -mtc -mta
  • New switches for Linux version for TAR archives:
    -snoi : store owner/group ids in archive or set owner/group ids from archive to extracted files.
    -snon : store owner/group names in archive
  • New -snz switch to propagate Zone.Identifier stream to extracted files (Windows).
  • New option “Propagate Zone.Id stream” in Tools/Options/7-Zip menu.
  • New “Options” window in “Add to archive” allows to select what metadata must be
    included to archive. Also it allows to select new option
    “Do not change source files last access time”.
  • Some bugs were fixed.

21.07 2021-12-26

  • 7-Zip now can extract VHDX disk images (Microsoft Hyper-V Virtual Hard Disk v2 format).
  • New switches: -spm and -im!{file_path} to exclude directories from processing
    for specified paths that don’t contain path separator character at the end of path.
  • In the “Add to Archive” window, now it is allowed to use -m prefix for “Parameters”
    field as in command line: -mparam.
  • The sorting order of files in archives was slightly changed to be more consistent
    for cases where the name of some directory is the same as the prefix part of the name
    of another directory or file.
  • TAR archives created by 7-Zip now are more consistent with archives created by GNU TAR program.
