Batch Renamer

A portable Windows utility that lets users safely rename multiple files at once, preview the results, and place the processed files into a dedicated output folder without modifying the originals.

Features

• Safe File Processing: Original files are never modified or deleted. Results are copied to a new folder.
• Drag & Drop / Browse: Easily add files to the queue or remove them individually.
• Live Preview: See exactly what the new filenames will look like before processing.
• Flexible Naming Patterns: Use {name}, {number}, prefixes, suffixes, and custom zero-padding.
• Validation: Detects duplicate names, invalid Windows characters, and inaccessible files before executing.
• AP / INBOX: Built-in announcement system (DTAP) for developer-to-user communication. Works gracefully offline.

Run from source

1. Ensure you have Python installed.
2. Install dependencies:

   pip install -r requirements.txt

3. Run the application:

   python run.py

(Or just double-click Launch.bat which will automatically set up a virtual environment and run it.)

Build the portable release

1. Install PyInstaller:

   pip install pyinstaller

2. Build the executable:

   pyinstaller --name BatchRenamer --onedir --noconsole run.py

3. Copy your Launch.bat into the newly created dist/BatchRenamer/ folder.
4. Zip the BatchRenamer folder and distribute it. Users can run it directly without installing Python.

Runtime Data

• The application stores the renamed files in: C:\Users\<username>\BR_results_<date>\
• If the folder already exists, it automatically appends _02, _03, etc., to prevent overwriting previous results.
• The application does not write any other local data or registry keys.

AP / INBOX

The INBOX button connects to a centralized announcement platform (DTAP) via Firebase.

• It requires an internet connection only to fetch announcements.
• If offline, it fails gracefully and the core renaming functionality remains 100% operational.
• The client is strictly read-only.
