rName

What is rName?

rName renames your files in bulk, calmly and without surprises. Drop in a folder, build your rules, and the table in the middle shows you every new name next to the old one right away: nothing is touched on disk until you say so. Everything happens right on your Mac, with no uploads and no account.

Key Features

• Eight rules to combine: the new name comes from a chain of rules applied in order, which you drag to reorder and switch off without removing
• Replace: find and replace text, with regular expressions and $1 groups too
• Insert, remove, number: a prefix, a suffix, or text at an exact position; a range of characters, the first or last ones, or a recurring pattern; running sequences with start, step, digits, and separator
• Letter case, dates, and extensions: lower case, UPPER CASE, Title Case, camelCase, PascalCase, snake_case, kebab-case; the creation date, the modification date, or today’s, in the format you pick; an extension to set, normalise, or remove
• Clean up the name: double spaces, accents, emoji, invalid characters, spaces turned into _ or -. Every rule can act on the name only, the extension only, or the whole file name
• Presets: save a chain and call it back with one click; four are ready to use — Tidy up names, Number in sequence, Date prefix, Web-friendly names
• The preview is always there: see the result next to the current name before you confirm
• Conflicts set aside: names that would collide, files already on disk, invalid characters, names that are too long. Those files stay out of the operation instead of breaking it
• Undo (⌥⌘Z): puts the files from the last operation back to their previous names
• One file at a time, too: double-click a row and type the name by hand; that file stops following the rules until you send it back to the computed name
• Swaps and capitalisation: swapping two names, or changing just the capitalisation, works, because rName goes through a temporary name and puts the original back if anything fails
• Permissions under control: renaming requires access to the folder holding the file; rName asks once per folder, and Settings › Permissions lists them all so you can revoke any of them whenever you like
• Built for macOS: drag into the window or onto the Dock icon, “Open With…” in Finder, keyboard shortcuts (⌘O, ⇧⌘O, ⌘⏎, ⌥⌘Z)
• Light, dark, or automatic appearance: interface in English and Italian
• No subscription: free, with no ads and no in-app purchases
