Article Introduction：Introduction In this article, we will look at a C# program to estimate folder size. On our computers, we store files in directories called folders. We will also see how to estimate the size of the folders present in the files. Merely calculating the file size is not sufficient to achieve our goals. Instead, we also need to calculate the size of folders and subfolders. The following article will explain how to calculate the size of a folder in three parts. The first part we need to know is the GetFolderSize method, which will give us the size of the folder. The second part is the FormatBytes method, which converts the size into a human-readable format. We will also briefly look at different approaches, which will be crucial for the further development of this article. Method we will
