Suppose you have a 600MB text file that you need to edit. If you have ever tried to open a large file in Microsoft's Notepad, you know that it can be frustrating to sit by while Notepad takes hours to open up your file. The truth is, Notepad is simply not designed to handle large files. Attempting to open a large file in Notepad can cause unbearably slow load times, lagging, and might even force Notepad to shut down.
There are several ways to get around Notepad's limitations. If you want to continue using Notepad, you can break up your file into several pieces, and then open the smaller files individually. However, this solution can be cumbersome and does take quite a bit of effort, especially if you need to recombine the files at a later time. Plus, breaking up the file requires that you have it open to begin with, and, as we know, that can be an issue.
To open and edit large files intact, you need a different text editor. Windows comes equipped with WordPad, something of a cross between Notepad and Microsoft Word. WordPad will open and allow you to edit much larger files than Notepad without lagging or crashing. However, although it can open larger files than Notepad, WordPad is designed as a lighter, simpler version of the Microsoft Word word processor, meaning that its features focus on formatting text rather than text editing. WordPad's rich text formatting is not ideal for programming or other uses that require plain text files.
