Обычно у меня нет проблем с резервным копированием сохраненных игр, но для этой конкретной игры я использую FreeArc, поскольку игра очень большая, поэтому Inno Setup не знает, какие файлы удалять. С FreeArc вам нужно использовать

[UninstallDelete]
Type: files; Name: "{app}"

Но эта конкретная игра хранит игры в{app}\data\save, Мне нужна функция, чтобы переместить эту папку куда-нибудь, удалить игру, а затем переместить ее обратно.

Вот мой код:

procedure DirectoryCopy(SourcePath, DestPath: string);
var
  FindRec: TFindRec;
  SourceFilePath: string;
  DestFilePath: string;
begin
  if FindFirst(SourcePath + '\*', FindRec) then
  begin
    try
      repeat
        if (FindRec.Name <> '.') and (FindRec.Name <> '..') then
        begin
          SourceFilePath := SourcePath + '\' + FindRec.Name;
          DestFilePath := DestPath + '\' + FindRec.Name;
          if FindRec.Attributes and FILE_ATTRIBUTE_DIRECTORY = 0 then
          begin
            if FileCopy(SourceFilePath, DestFilePath, False) then
            begin
              Log(Format('Copied %s to %s', [SourceFilePath, DestFilePath]));
            end
              else
            begin
              Log(Format('Failed to copy %s to %s', [SourceFilePath, DestFilePath]));
            end;
          end
            else
          begin
            if CreateDir(DestFilePath) then
            begin
              Log(Format('Created %s', [DestFilePath]));
              DirectoryCopy(SourceFilePath, DestFilePath);
            end
              else
            begin
              Log(Format('Failed to create %s', [DestFilePath]));
            end;
          end;
        end;
      until not FindNext(FindRec);
    finally
      FindClose(FindRec);
    end;
  end
    else
  begin
    Log(Format('Failed to list %s', [SourcePath]));
  end;
end;

procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
Begin
  if (CurUninstallStep = usUninstall) and
     DirExists(ExpandConstant('{app}\data\SAVE')) then
  begin
    if MsgBox('Do you want to delete all save games?',
         mbConfirmation, MB_YESNO) = IDYES then
      begin
        DelTree(ExpandConstant('{app}'), True, True, True);
      end
    else
      begin
        DirectoryCopy(ExpandConstant('{app}\data\SAVE'), ExpandConstant('{app}\SAVE'));
        Deltree(ExpandConstant('{app}\data'), True, True, True);
        DirectoryCopy(ExpandConstant('{app}\SAVE'), ExpandConstant('{app}\data\SAVE'));
      end
  end;
End;
