BadRename
A batch file renamer: pick a rule and see every new name before any file is renamed.
About
A batch rename tool for Windows, macOS and Linux, drawn with MyGo's native UI, with no webview and no Node.js. New names come from one of four rules: a template with the original name and serial numbers, plain replace, add or delete text, or a regular expression. Every new name is shown before anything touches the disk, and on a conflict it can ask, overwrite, skip or auto-rename.
