Renaming files/names in bulk, any smarter solution?
export into a CSV (unicode UTF-8 or any other 8bit encoding, not UTF-16): two columns, separated by ; (assuming there is no ; in a file name) 
open Terminal
change to folder containing the files
run perl -pi -e 's/\r\n/\n/;' LISTOFNAMES.csv to fix CRLF issues
run while IFS=\; read old new; do mv "$old" "$new"; done &lt; LISTOFNAMES.csv


PS: This will overwrite existing files if the new name already exists.

PPS: Test this on a temporary folder with just a few files first (and make sure you have a recent backup)
