Prerequisites & Requirements

Before starting the batch renaming process, ensure you meet the following requirements:
  • •macOS version 10.14 (Mojave) or later is recommended for optimal features.
  • •Sufficient permissions to modify the files you wish to rename.
  • •No files should be open or in use during the renaming process.
  • •Backup important data to prevent accidental loss during renaming.

Method 1: Using Finder

This method is ideal for users who want a quick and straightforward way to rename multiple files without additional software.
  • •Step 1: Open Finder and navigate to the folder containing the files you want to rename.
  • •Step 2: Select all the files you wish to rename by holding down the Command (⌘) key and clicking each file, or press Command (⌘) + A to select all.
  • •Step 3: Right-click on the selected files and choose 'Rename X Items...' from the context menu.
  • •Step 4: In the Rename dialog, choose one of the options: 'Replace Text', 'Add Text', or 'Format'. Fill in the required fields based on your choice.
  • •Step 5: Click 'Rename' to apply the changes.
  • •Step 6: Verify the changes by checking the filenames in Finder.

For macOS 10.15 (Catalina) and earlier

The batch renaming feature is available but may lack some advanced options found in later versions.

Method 2: Using Automator

Automator provides a more advanced way to batch rename files, allowing for custom workflows.
  • •Step 1: Open Automator from the Applications folder.
  • •Step 2: Choose 'New Document' and select 'Workflow'.

  • •Step 7: Click 'Run' to execute the workflow.
  • •Step 8: Check Finder to confirm the files have been renamed.
