The B_W image format is associated with Image Lab, a software pack that provides several features for capturing and processing images. A B_W file contains a black-and-white image created with this software and is currently considered a rare format, compatible with only a limited number of image handling programs.
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 B_W files as once.
