<code>File.exists?</code> only checks if a file exists; it can be a regular file, a directory, or something else. <code>File.file?</code> or <code>File.directory?</code> checks for a regular file or a directory. Ruby also allows <code>FileTest.file?</code> or <code>FileTest.directory?</code>.
<lang ruby>File.file?("input.txt")
