Duplicate Searcher

Duplicate Searcher

The aim of this Duplicate Searcher project is to produce a C# based application that will scan a file system or file repository for duplicate files using CRC

The different types of comparison will be:

File System with itself e.g. D:\data with D:\data

File System with an other file system e.g. C:\data with D:\data

File System with a file repository

The software will produce a list of duplicate files i.e. files with matching CRC and their locations in both source and destination.

The file repository will have a simple interface that will allow you to retrieve files. A sample set of classes to retrieve files is included below.


The following deliverables are required:

1. A C# Class Library to perform the comparisons listed above.

2. A command line program to drive the above library

3. A concrete implementation for the file repository so testing may be performed. For example, FTP may be used as a repository or even an other file system may be used. This only has to be good enough for testing.

4. Optional – A WPF or Windows Forms application to display the CRC matches.


/// <summary>

    /// Reads files from a repository

    /// </summary>

    public abstract class RepositoryReader


        private string repositoryIdentifier;


        public RepositoryReader(string repositoryIdentifier)


            [url removed, login to view] = repositoryIdentifier;



        /// <summary>Connects the repository</summary>

        /// <returns>true if connection successful</returns>

        public abstract bool connect();


        /// <summary>Returns the next item in the repository</summary>

        /// <returns>null if there is no next item</returns>

        public abstract RepositoryItem next();



    public abstract class RepositoryItem



        public abstract string id();

        public abstract string location();

        public abstract string title();

        public abstract string fileName();

        public abstract Stream getFile();
