ICA files are associated with IOCA (Image Object Content Architecture), a graphics format used by some archaic IBM computer models. ICA images often contain scanned images, which can be black-and-white, grayscale or colored. The ICA format is currently considered obsolete and rare, so converting it to a more accessible format might be the best option.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple ICA files as once.
