Preview before you commit
See exactly what each file becomes - changed, unchanged, or needs attention - before a single name is touched.
Rename
Preview safe bulk renames before touching your files.
Rename Studio takes the terror out of bulk renaming - add files or folders, build a numbering or pattern scheme, and watch a full preview flag every change, every collision, and everything left alone, so you only commit once the plan is clean.

Can it continue numbering after existing files?
Yes. Numbers-only mode can start after the highest numeric filename in each selected folder.
