There seems to exist a Japanese software called ClippingSticker that can export Picture Clipping files (.pictclipping) from Mac OS X to many other bitmap formats, including the JPEG format (.jpg, .jpeg). Without such conversion, it will be very hard to work with .pictclipping files on Windows machiens.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
