BC Renamer

BC Renamer is a powerful, lightweight Java utility designed to simplify the process of renaming large groups of files. Whether you are organizing photo collections, music libraries, or development assets, BC Renamer provides a clear, real-time preview of every change before you commit to it.

• Live Preview & Conflict Detection: See exactly how your files will be renamed in real-time. The app automatically flags filename conflicts in red to prevent accidental data loss. Flexible Renaming Rules: Combine multiple rules—replace text, insert prefixes/suffixes, change case (UPPER, lower, First Capital), or remove parts of the filename entirely.
• Smart Auto-Numbering: Easily add sequences to your files with customizable starting points, increments, and zero-padding (e.g., 001, 002).
• Metadata Integration: Automatically insert dates into filenames using File Creation, Last Modified, or even EXIF dates from your photos.
• Advanced Search & Replace: Support for Regular Expressions (Regex) and case-sensitive matching for precise string substitution.
• Dynamic Directory Tree: Navigate your folders easily with the built-in system tree and use Drag and Drop to load directories instantly.
• Safety First: The application uses a two-step internal renaming process to ensure maximum reliability even during large batch operations.
• Portable & Cross-platform: No installation required. Runs seamlessly on Windows, macOS, and Linux.
