The iSqFT Tiff Converter program makes use of a conversion program from Cartesian Products Inc. to automate the otherwise manual conversion of CPC and CPI files. If you wish to perform conversions manually, you can make use of the files included in the "CPC Manual Convert.zip" file located in this program directory on your hard drive. The manual conversion of CPC and CPI files is exlained on Cartesian's web page: http://www.cartesianinc.com/Products/CPCTool/.
To use the program you should navigate to the folder where the CPC files have been downloaded on your computer in the left side of the window labeled Source Directory Containing Files To Be Converted.
Then you can navigate to the folder where you want the converted files to be placed in the right side of the window labeled Destination Directory for Converted Files. If you want the converted files to be placed in the same folder you can click the arrow in the middle of the window to automatically select that folder as the destination.
