ScrubPony 1.3.0
Bulk folder clean now shows what metadata each file carried, sorts the files that carry metadata to the top, and remembers already-clean, unchanged files so a re-scan of the same folder skips them (with a count shown so you can see it working). PNG text metadata (the tEXt and iTXt chunks PNGs use instead of EXIF) is now read and shown in the details too.
Same as before: on the device, no broad file permission, originals untouched unless you choose in place.
