Actually, they probably are TIFF files, just not the kind most software
expects. TIFF is a packaging format for image data, and can encapsulate
anything including proprietary data. In that respect, it's like AVI for
video files. You can wrap JPEG compressed data in a TIFF file if you want.
And indeed, the new Adobe DNG format is a TIFF file. It's just that the most
common use of TIFF is to wrap uncompressed or losslessly compressed image
data, so that's all most software supports.

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
