markdouglasgrant, my conclusion is if there is metadata in your files for the X & Y resolution, then you can visually use Bridge or use a Bridge metadata export script and a spreadsheet (or a script to sort to folder or collection or smart collection etc) or ExifTool to report on this value. If your files are “blank” where this metadata tag should be, then you will likely have to use another method. If you don’t wish to use a batch action to set this 300ppi resolution value, then I would use ExifTool: exiftool -XMP-tiff:XResolution='300' -XMP-tiff:YResolution='300' -XMP-tiff:ResolutionUnit='inches' 'MAC OS/FILE/or/TOP LEVEL DIRECTORY PATH HERE' This code is formatted for the Mac OS, MS Windows users would use straight double quote marks “ and the expected \ file path formatting. This is a basic command, it is further possible to overwrite the originals instead of creating a backup _original copy of each file, and to recursively process into sub folders, to only proces specific file types and to exlude specific sub folders under the top level directory being recursively processed. Another example, ExifTool could recursively scan a top level/sub-level directories for PNG images that were missing the resolution metadata tag and conditionally label them with an Adobe Bridge “label” marked “review” (overwriting the original files with no _original copy created): exiftool -r -overwrite_original_in_place -if 'not defined $XMP-tiff:XResolution' -XMP-xmp:Label='Review' 'MAC-OS/FILE/or/TOP LEVEL DIRECTORY PATH HERE' -ext .png Or, rather than labelling the files with missing resolution metadata, these files could be conditionally processed to add in the missing metadata: exiftool -r -overwrite_original_in_place -if 'not defined $XMP-tiff:XResolution' -XMP-tiff:XResolution='300' -XMP-tiff:YResolution='300' -XMP-tiff:ResolutionUnit='inches' 'MAC OS/FILE/or/TOP LEVEL DIRECTORY PATH HERE' -ext .png
