El Capitan tip: change name on many files
Have you ever wanted to change the name (whole or part) of a bunch of files? This have been tricky in Finder before but in El Capitan its easy.
Just highlite the files you want to change and choose "Change name on xx objects" from the archive menu. I choose to substitute "bild" to "skärm" and here is the result
Super easy but VERY handy..........
