How to Rename Files in the Finder
The macOS Finder has a quite limited but very useful means to rename files. I use this feature just about every day multiple times for various things.
- Select the items to be renamed
- Right click (or control click); choose
- Using to replace text with other text or or .
- Click .
Job done. The negatives include no ability to use regex; the feature is very useful but also has no depth or elegance for more complex actions.
