What it does
Point it at a folder, set a naming pattern, and review the new names in a preview list. Nothing is written until you run the job. It flags duplicates, invalid names, and targets that already exist.
You can rename files in place, copy them to another folder under the new names, or move them there. Prefix and suffix sequences can be numbers or letters. You can also search and replace text, strip characters, change case, and keep or change the extension.
Modes
- Rename in place
- Copy and rename
- Move and rename
