Hi,
from a selection of multiple image files, most get skipped and the Show Log button does not appear to do anything.
Using another tool (EXIF Purge), I could remove the exif data without a problem.
Background for this need, is that in both Explorer and MC many files would not show a thumbnail. I assume this is due to a problem with the embedded EXIF thumbnail. I could not find an easy way to bulk regenerate them, so deleting the EXIF I believe forces Windows to make its own thumbnail, which worked.
