Hi is there any chance to swap zip compression format to more modern 7zip? This would save a lot of disk space for us. 

Thanks for great job

Ive done it manually:

1- You have to put the 7za.exe (c:\program files\7-zip\) inside the util folder in your exodos instalation.

2- Delete the file unzip.exe from the util folder.

3- Rename the 7za.exe to unzip.exe.

4- You'll have to manually edit each install.bat file inside the !dos folder inside your games folder.

Example: 10000 Pyramide:

@echo off
set CONF=%CD%
cd ..
cd ..
cd ..
IF EXIST ".\Games\$100000P\" GOTO dele
:unzip
copy .\util\unzip.exe .\Games\unzip.exe
cd Games
unzip "$100,000 Pyramid (1988).zip"

Will become:

@echo off
set CONF=%CD%
cd ..
cd ..
cd ..
IF EXIST ".\Games\$100000P\" GOTO dele
:unzip
copy .\util\unzip.exe .\Games\unzip.exe
cd Games
unzip x "$100,000 Pyramid (1988).7z"

5- Create a batch file:

Open a new txt file from notepad ;

Paste this command lines to the txt:

:: Q:\Test\2018\10\11\SU_1365974.cmd
@Echo off
Set  z7="C:\Program Files\7-Zip\7z.exe"
Set "z7o=a -y -r -t7z -m0=lzma2 -mx=9 -mfb=128 -md=512m "

for %%F in (*.rar *.zip) do (
  %z7% x -y -o"%%F_tmp" "%%F" *
  pushd %%F_tmp
  %z7% %z7o% ..\"%%~nF".7z * ||(pause)
  popd
  rmdir /s /q "%%F_tmp"
  del "%%F"
)

and save it as zipto7z.bat

6 - Put the zipto7z.bat inside your exodos games folder.

7 - Run the batch. It takes about 48 hours to convert.
