What Can Batchio Rename on Your Mac?

How Do Batchio's 12 Rule Types Work Together?

Rule chaining makes complex renaming operations possible without writing scripts. A photographer might combine Date Insertion (to add the shoot date), EXIF Metadata (to append the camera model), and Numbering (to add a sequence). Each rule processes the filename that the previous rule produced. Our guide on how to batch rename files on Mac walks through the full workflow from start to finish.

Batchio detects naming conflicts before renaming starts. If two files would end up with the same name, a warning icon appears in the preview. You can choose to block the operation, auto number duplicates, or skip conflicting files.

How Does Batchio's Live Preview Work?

The live preview is the core differentiator that sets Batchio apart from other Mac batch renaming tools. Renamer, Name Mangler, and Better Rename all require you to click a separate preview or apply button. Batchio updates the preview as you type, adjust sliders, or toggle rule options.

For large file sets with 500 or more files, Batchio debounces preview updates to maintain smooth performance. The preview still updates within milliseconds of your last input.

What Does Batchio Pro Add?

Saved presets let you store entire rule chains and reapply them with one click. Batchioincludes built in sample presets like "Clean up downloads" and "Photo organizer" to demonstrate common workflows.

Folder renaming lets you rename the folders themselves, not just the files inside them. Switch the Rename scope to Folders or Both and every rule works on your folder names, with the same live preview and undo. See the folder renaming feature for the full breakdown.

Folder automation watches designated folders for new files and applies a preset automatically when files appear. This works in the background, making it ideal for automating download folder cleanup or organizing files as they arrive from a camera import.
