OPL BIN/CUE > iSO Converter?

Hello Guys,

Im currently playing with my old FAT PS2 and build an HDD inside.
The OPL Manager is a really nice tool, but you can convert only 1 after 1 file.

Is there any Program available to convert some files in a row? Multiple files and not 1 by 1?

I tried already googling, there are some other iso convert available, but the most seem to do it also 1 by 1

Thanks in advance for your support

Regards,
