Go folders and subfolder recursively and convert

As it turns out, we're dealing with Kofax's implementation of TIFF with JPEG compression.

Unfortunately, Windows Picture and Fax Viewer doesn't like JPEG-compressed TIFFs.

Wikipedia (Windows Photo Viewer » Evolution) wrote:Windows Picture and Fax Viewer was also capable of viewing multi-page TIFF files, (except those that employ JPEG compression) as well as annotating the TIFF files.

If the goal is to make these TIFFs compatible with Microsoft's viewer, resaving them with a different compression would indeed make sense.

Fortunately for us, XnConvert doesn't rely on the filename extension to recognize a format. However, files without extension aren't categorized as images…

The only way is to use in xnViewMP, recursive display, select all and batch convert

… which is why they are ignored by the Add folder... command.
