Chapter 8: File and Stream I/O

In this chapter, you will learn how to improve directory, file, and streaming performance. You will also learn how to efficiently enumerate directories, process small and large files, perform asynchronous operations, use local storage, handle exceptions, and work with memory efficiently.

We will cover the following topics in this chapter:

• Understanding the various Windows file path formats: This section provides information on the different file path formats that you will encounter on the Windows operating system. Also covered is the 256-character file path limit on Windows, and techniques that cover how to remove this limitation.
• Considering improved I/O performance: In this section, we will be benchmarking some code to see which method of coding performs fastest when it comes to calculating directory sizes and moving files. Plus, we will look at how to read and write files asynchronously.
• Handling I/O operation exceptions: We will...
