If you import some images in PureRef, save the scene, delete the original files (the images from disk so they are available only in the .pur scene), export Selected Images from PureRef to desktop and then you try to import those exported images in Photoshop, you'll get (I get this):

Could not complete your request because the file-format module cannot parse the file.

So the files somehow corrupts, is there a solution? I guess it's a bug.

(Export Cropping: Disabled; No Override Name)

Thanks again for the detailed description. We tried it with your scene but it seems to work fine for us. Did you export the image to some specific place, like a network drive or something similar?
