BC Renamer

BC Renamer is a tool written in Java that facilitates mass file renaming through combinable rules, real-time preview, and conflict detection. The program integrates support for EXIF metadata, regular expressions, and an auto-numbering system for organizing image collections, music files, or development assets without requiring installation on Windows, macOS, and Linux.

• Real-Time Preview. The interface immediately displays the result of the applied rules on file names. Any conflicts between names, such as duplicates or invalid characters, are marked in red to prevent data loss before executing the rename.
• Combinable Renaming Rules. Users can stack multiple operations in a single session: replace text, insert prefixes or suffixes, change to uppercase/lowercase, apply title formatting (first letter capitalized), or remove specific parts of the original name.
• Intelligent Auto-Numbering. Allows adding custom numerical sequences with control over the starting value, increment, and zero-padding (e.g., 001, 002) to maintain a specific order in batches.
• Metadata Integration. BC Renamer can automatically insert dates into file names obtained from the creation date, modification date, or EXIF metadata of photographs, facilitating chronological organization.
• Advanced Search and Replace. Supports regular expressions (Regex) for complex and precise text substitutions. Includes an option to distinguish between uppercase and lowercase during the search.
• Dynamic Directory Tree. Integrated navigation through the system's folder structure to quickly locate working directories. Supports drag and drop functionality to load folders directly into the tool.
• Internal Two-Phase Renaming Process. The software implements a mechanism that separates simulation from execution, guaranteeing file integrity even in massive operations with hundreds of items.
• Portable Cross-Platform System. Being developed in Java, it requires no installation and works identically in Windows, macOS, and Linux environments without additional external dependencies.
• Text Insertion at Specific Positions. Ability to add characters or words at specific indices of the file name, allowing surgical modifications without altering the rest of the text.
• Deletion of Characters or Ranges. Option to delete specific sections of the name, either by defining a range of positions or by removing unwanted characters such as underscores or redundant spaces.

The development history of BC Renamer dates back to 2025, when the ByteCove team identified the need for a batch renaming tool that offered total control without relying on complex scripts. The program is written entirely in Java, which guarantees its portability and consistent performance on major operating systems. Since its first version, the developers have prioritized precision in file name manipulation and error prevention, implementing gradual improvements based on direct experience with digital organization workflows.
