Notepad, the basic text editor that comes with Windows, is by nature a pretty bare-bones program. For the simplicity of Notepad with a few extra features--including support for NFO files--try NFOPad. For the most part, this simple program duplicates the experience of using Notepad, but it throws in a few fun and useful options that make it more versatile.
NFOPad's interface is more or less an exact copy of Notepad's; the only difference is that Notepad's Format menu has been replaced with a Settings menu in NFOPad. In addition to the built-in ASCII fonts for NFO files, the program gives users the capability to follow links within documents, customize the background and text colors, set auto width parameters, determine tab size, and more. NFOPad also has a few extra editing features, including the capability to delete entire lines of text and to change text case. The program doesn't have a Help file per se--there's a Help menu, but it only contains two FAQs--but for the most part NFOPad is self-explanatory; it's very much like using Notepad. Users who aren't familiar with NFO files will need to look elsewhere for information about them, as NFOPad assumes a level of familiarity with them, but the program can still be used as a text editor by users who aren't familiar with NFOs. In the end, NFOPad is a pretty no-frills text editor without a ton of features, but its additional NFO-handling capabilities are sure to please users who need to create software documentation.
NFOPad installs and uninstalls without issues. We recommend this program to all users.
