The conversion of the file C2D to ISZ will allow you to edit a file using other software than before. The conversion C2D to ISZ is particularly helpful in cases where you want to give certain features to the data in the C2D file, and all the programs that support the C2D format do not have the possibility to introduce the desired changes.
Just download one of the programs from the list and install it on your computer. After starting the program, select C2D file that you want to convert. Then select the target format (in this case ISZ) and follow the instructions. Save the converted ISZ file in the selected location. From this moment you can open the ISZ file with all the programs that you will find here.
