A FEW ANSWERS

A few things to know.

All questions
Can I restore the original names?

Runs are recorded in history, where you can undo name changes. Files moved, deleted, or renamed in another app may not be recoverable by this operation. Check the result details.

Will my file contents change?

Normal renaming changes the name. Separate encoding and line-ending tools change file contents. Check the operation you select before running it.

Which Macs are supported?

Apple silicon and Intel Macs running macOS 14 or later.
