ChangeExtension and Resize

A .NET 6.0 console application to rename file extensions from .JPG to .jpg, rename the files with a sequential number, and resize the images to 30% of their original size in a specified directory.

Prerequisites

• .NET 6.0 SDK
• ImageSharp Library (installed with dotnet add package SixLabors.ImageSharp)

Usage

1. Navigate to the Project Directory: Open a command prompt or terminal and navigate to the directory containing the ChangeExtension project.

2. Install the ImageSharp Library: Run the following command to add the ImageSharp library to your project: dotnet add package SixLabors.ImageSharp

3. Build the Project: Run the following command to build the project: dotnet build

4. Run the Application: Run the application with the following command, replacing <directoryPath> with the path to the directory containing the .JPG files: dotnet run -- <directoryPath>

For example: dotnet run -- "C:\Users\Gates\Desktop\1"

This will:

• Rename all files with the .JPG extension in the specified directory to have a .jpg extension.
• Rename each file to a sequential number starting from 1.
• Resize each image to 30% of its original size.

Example

To rename and resize all files with the .JPG extension in the directory C:\Users\Gates\Desktop\1, use the following command: dotnet run -- "C:\Users\Gates\Desktop\1"

This command will loop through all the files in the C:\Users\Gates\Desktop\1 directory, change the extension of files with .JPG to .jpg, rename each file to a sequential number, and resize each image to 30% of its original size.

Note

Be sure to backup your files before running the application to prevent data loss in case of an error.
