How to find duplicate folders using csharp 5 Best methods

Finding duplicate folders is one of the complicated tasks. It can take lots of time if we start searching folders manually. 

Problem: how to find duplicate folders using csharp 5 Best methods

Just take an example: If we have a hard drive of 1 TB. And it is full of lots of folders and files. If we start searching folder names with search operation in our operating system. Then obviously it will take lots of time in searching. 

Solution: 

Another way to solve this problem is by using a programming language such as a shop to find out duplicate folders. Today I am going to show you some of the best methods to find out duplicate folders using C Sharp. These methods are: 

1) Using hash values of folders 

Every folder in our computer system has a numerical value. This is the medical value known as checksum for hash value. Using hash values we can find duplicate folders in our computer system. 

The process is very simple and easy to use. We can compute the hash values of two or multiple folders with each other and compare their values. To compare their values we can use any programming language such as C Sharp. 

2) By using the folder name

Searching for duplicate folders with folder names is not a pretty good idea. It takes lots of time and can give us wrong results. 

We can be done this process by using the search feature in our operating system. This process can be good if we have a few folders or files in our operating system. 

3) Using brute force approach 

The brute force approach is another way to find out duplicate folders in a hard disk or data drive. This process compares the content of each subdirectory and checks the same sets of files if present in both folders.  According to different experts, this method is not much good as Hash Function. 

4) Using file indexing tools 

Till now finding duplicate folders is much more amazing with file indesing tools. This method uses an index of all files and folders in the computer system. These are all indexes of files that are used to find duplicate folders. 

This method is so much amazing and efficient because it is more powerful than finding the hash values of folders. In this article, I am going to show you c Sharp program to find out duplicate folders using the hash values of folders. 

You need to follow these steps: 

1. We have to iterate through all subdirectories if we find out folders in a given directory. 
2. While iteration we have to compute the hash of the fires using the cryptographic Hash Function. You can use SHA-256 to compute the hash of the files. 
3. While iteration and getting hash values we have to store them in a dictionary. It is a pretty good idea because we can compute all hash values of files and folders through this dictionary. 
4. The last process is to find duplicate hash values of folders within the dictionary that we created. 

The dictionary will contain the list of all subdirectories with your hash values and we can easily find out duplicate folders. 

Here is some code for this program.

This code will find all the duplicate folders in the root directory and its subdirectories and print their names to the console.
