Script

Thanks to Abelenki for the script.

Instructions:

  1. Replace D:\emulation\ExtraStuff\7-Zip\7z.exe with 7-Zip location in your system.
  2. Put Mass Convert 7Z To ZIP.cmd to your folder with 7Z files.
  3. Run Mass Convert 7Z To ZIP.cmd from this folder (it will convert all you 7Z/T7Z files to standard ZIP files).


The script, which should be saved as "Mass Convert 7Z To ZIP.cmd": 

set sevenzip=D:\emulation\ExtraStuff\7-Zip\7z.exe
for %%F in (*.7z) do (
REM Extract...
%sevenzip% x "%%F" -o"%%F contents"
REM Change directory, create zip of contents of directory...
CD "%%F contents"
%sevenzip% a -tzip "../%%~nF.zip" *
CD ..
REM Delete the old files
DEL "%%F" /F /Q
RMDIR "%%F contents" /S /Q
)


For Linux and Mac OS X

Thanks to Obiwantje and filou for the script.


Instructions:

  • In Linux it needs both coreutils and parallel as well:

sudo apt-get install moreutils

sudo apt-get install parallel


  • In Mac OS X, it needs coreutils and parallel to be installed.

brew install coreutils parallel


  • By default it uses N+1 cores with N the numbers of cores of the computer. As it can be memory hungry, it is possible to fix the number of attributed cores with the MAX_CPU variable.


Script

The script follows: 


#! /bin/bash
# 7z_to_tzip.sh source_dir target_dir


IN_DIR=$(readlink -f "$1" 2>/dev/null || realpath "$1")
OUT_DIR=$(readlink -f "$2" 2>/dev/null || realpath "$2")
MAX_CPU=$(( $(grep -c ^processor /proc/cpuinfo 2>/dev/null || sysctl -n hw.ncpu) + 1 ))
#MAX_CPU=4


archive_convert(){
  IN_DIR=$1
  OUT_DIR=$2
  SOURCE_FILE=$3
  TMP_DIR=$(mktemp -dt tmp.XXXXXXXXXX)
  cd "$TMP_DIR" || exit 1
  TARGET_DIR=$(dirname "${SOURCE_FILE/$IN_DIR/$OUT_DIR}")
  TARGET_FILE="${TARGET_DIR}/$(basename "${SOURCE_FILE}" .7z).zip"
  if [ ! -d "${TARGET_DIR}" ]; then
    mkdir -p "${TARGET_DIR}"
  fi
  if [ ! -f "${TARGET_FILE}" ]; then
    7z x -y "${SOURCE_FILE}"
    zip -1 -r "${TARGET_FILE}" .
  fi
  cd "$TMPDIR" || exit 1
  rm -rf "$TMP_DIR"
  trrntzip "${TARGET_FILE}"
  return $?
}


if [ ! -d "${OUT_DIR}" ]; then
    mkdir -p "${OUT_DIR}"
fi


export -f archive_convert
LOCAL_TMP="$(pwd)/tmp"
if [ ! -d "${LOCAL_TMP}" ]; then
    mkdir -p "${LOCAL_TMP}"
fi
find "${IN_DIR}" -type f -name '*\.7z' -print0 | parallel -q0 --tmpdir "${LOCAL_TMP}" -j${MAX_CPU} archive_convert "${IN_DIR}" "${OUT_DIR}" {}
#rm -r "${LOCAL_TMP}"
