Predefined rules and templates, shown as real before-and-after examples you can adapt to your own files.
Bulk Rename Utility applies a stack of small rules to every selected file in order — remove, add, replace, renumber, change case, adjust dates — and shows you the combined result in a live preview column before anything is written to disk. You can mix multiple rules together for one renaming pass.
Rule stack: remove the IMG_ prefix, insert a descriptive name, then append a sequential number.
Rule stack: replace underscores with spaces, apply title case, and move the track number to the front using a template.
Rule stack: extract the file's last-modified date and insert it at the front in ISO format, then remove inconsistent trailing text.

| Replace | Swaps one piece of text for another across all selected files. | Turning underscores into spaces. |
| Add | Inserts fixed text at the start, end, or a specific position. | Adding a project or trip name to every file. |
