Run renamer in the directory you want to rename things, then

• edit Filter to select which files to edit (it's a regular expression)
• edit Rename to to define how files should be renamed, you can use the following magic placeholders:
  • [N] - name without extension, you can select the substring with:
    • [N2-5] - filename without extension, characters from 2 to 5 (counting from 1)
    • [N-2-5] - filename without extension, characters from 2 from the end to 5 (counting from 1)
    • [N2--5] - filename without extension, characters from 2 to 5 from the end (counting from 1)
    • [N2,5] - filename without extension, 5 characters characters starting from 2 (counting from 1)
    • [N-2,5] - filename without extension, 5 characters characters starting from 2 from the end (counting from 1)
  • [E] - just extension, substrings working like with N
  • [P] - parent directory name, substrings working like with N
  • [G] - grandparent directory name, substrings working like with N
  • [C] - counter (which file it is), by default starting from 1, by step 1, without appending any zeroes, can be customized with:
    • [C:10] - counter starting from 10
    • [C;5] - counter starting from 1 step by 5
    • [C:10;5] - counter starting from 10 step by 5
    • [C%3] - counter starting from 1 step by 1, formatted with 3 digits
    • [C:10;5%3] - counter starting from 10 step by 5, formatted with 3 digits
  • [D:date format] - date format following Java's DateTimeFormatter convention
  • $0, $1, $2 - groups from the regular expression match
    • Groups are extracted only from the first match! Use ^ and $ if you want to match the whole line!
• check if there are no issues, if it's OK, accept rename with Enter
• or abort with Esc
