| + | |||
| + | In the //with// box, enter a replacement string to replace the file name part that matches the regular expression with. The replacement string can use ''$x'' syntax to refer to the ''x''-th group (subexpression in parentheses) captured by the pattern. | ||

| + | On the image, you can see a pattern (''(\d{4})-(\d{2})-(\d{2})'') and a replacement string (''$2-$3-$1'') that change date stamp in file names from the ''yyyy-mm-dd'' format to the ''mm-dd-yyyy'' format by changing an order of captured groups. | ||

| + | Check the //Preview changes// checkbox to see and confirm the changes in file names before actually renaming the files. | ||
