Batch Rename Files
Rename hundreds or thousands of files in a single pass. Add prefixes and suffixes, replace text, renumber sequences, and apply rules to entire folders at once — far faster than renaming files one by one in Finder.

Features
Everything you need for clean filenames
FileWrench focuses on one problem — fixing and organizing file names in bulk — and solves it completely.
Fix Unicode Filename Errors
Files copied from Windows, Linux, or old backups often show garbled names like — or �. FileWrench detects and repairs Unicode encoding errors (Mojibake) so your filenames display correctly again.
Resolve Special Character Broken Files
Filenames with characters that macOS handles badly — slashes, colons, control codes, and mixed encodings — become broken or invisible files. FileWrench resolves them into clean, fully compatible names.
Bulk File Modify & Organize
Fix extensions, normalize name casing, clean up spaces and separators, and tidy large file libraries in bulk. Turn a messy downloads folder or project directory into something organized in minutes.
Lightweight & Native Mac App
