Use Automator to drop one letter in the naming
You could use a Run Shell Script action like this:



for f in *;do [[ $f =~ (.+ [0-9]+)x([0-9]+ .+) ]]&amp;&amp;mv "$f" "${BASH_REMATCH[1]}${BASH_REMATCH[2]}";done;exit 0

Or if the filenames don't contain other x characters, you could replace the script with for f in *;do mv "$f" "${f/x/}";done.
