If you like to read data in from text files or save lots of data to text files, you’ve probably discovered that Window’s default text reading program, Notepad, sucks. It can’t open large (MB or larger) text files, sucks at formatting, and seems slow. I prefer the freely downloaded program Notepad++. It can handle large files with ease, allows multiple text files to be open in the same program, highlights all equivalent words if a word is highlighted, gives line numbers, and probably has a ton of other capabilities that I’m not familiar with. You should upgrade to Notepad++.
