+## How Many Bytes Does a File Need?
+
+To determine how much memory a file requires, you need to consider its contents. For example, in a text file, the size is determined by the number of characters (including spaces and punctuation). Each character typically requires one or more bytes of storage.
+For other types of files, like images, the calculation is different. For an image on a 160x120 pixel screen, the total memory needed would be the total number of pixels (160 * 120) multiplied by the number of bytes required to store the color of each pixel (which depends on the bits per pixel, or BPP).
