csRenamer

csRenamer is a Windows desktop application built with WPF and .NET 8.0, designed for batch renaming files with ease. It provides a flexible and user-friendly graphical interface for renaming files using patterns, substitutions, insertions, deletions, and more — all with instant preview.

This project is a C#/.NET 8.0 clone of pyRenamer, recreated using Windows-native technology to bring the same powerful renaming functionality to the Windows ecosystem with a modern UI.

Features

csRenamer will support the following features:

• Keep or change file extensions during rename
• Rename files based on patterns (e.g., rename 1-a.txt → a-1.txt using {#}-{X}.txt)
• Insert characters at specific positions
• Delete characters from specified positions
• Replace matching characters or sequences
• Convert accented characters to plain ones
• Change capitalization (UPPERCASE, lowercase, Title Case)
• Replace or remove dots, dashes, and spaces
• Remove duplicated characters or symbols
• Manually rename individual files
• Live preview of all filename changes before applying

Requirements

• Windows 10 or later
• .NET 8.0 Runtime
• Optional: Visual Studio 2022+ for development

Build and Run

To build and run csRenamer locally:

# Clone the repository
git clone https://github.com/yourusername/csRenamer.git
cd csRenamer

# Build the project
dotnet build

# Run the application
dotnet run --project csRenamer

Installer

For regular users, a pre-built Windows installer will be provided — no setup or compilation required. Just download, install, and start renaming!

The installer will be available on the Releases page.

About This Project

csRenamer is a personal reimplementation of the original pyRenamer application. It aims to maintain feature parity while taking advantage of the Windows Presentation Foundation (WPF) framework for a polished and responsive user experience. It’s built for users who want to perform complex batch renaming without relying on command-line tools.

Future Plans

Some upcoming features under consideration:

• Music and image file renaming using metadata (ID3, EXIF, etc.)
• Drag-and-drop file support
• Regex-based renaming
• Dark mode and UI themes
• Multi-language UI (localization)
