MergeArchive - A Basic Tar-Like File Format in C#

MergeArchive is a simple C# program that implements a basic tar-like file format with a command-line interface (CLI) for packing and unpacking files. This project is intended for educational purposes and serves as a minimal example.

Usage

Pack Files

To pack files into a MergeArchive:

dotnet run pack myarchive.mar file1.txt file2.png

Unpack Files

To unpack files from a MergeArchive:

dotnet run unpack myarchive.mar output_folder

List Contents

To list the contents of a tar-like archive:

dotnet run list myarchive.mar

Code Explanation

The code consists of a simple C# console application with two main functionalities:

1. Packing Files:

   • The Pack method takes a list of file paths and creates a tar-like archive.
   • It uses GZip compression and stores file names along with their content sizes.

2. Unpacking Files:

   • The Unpack method extracts files from the tar-like archive to a specified output folder.
   • It reads the archive, recreates the files, and stores them in the output folder.

3. Listing Contents:

   • The ListContents method displays the names and sizes of files within the tar-like archive.

Requirements

• .NET Core SDK
