Importing and exporting general data.
Some common formats for tabular data.
Import and Export can handle not only tabular data, but also data corresponding to graphics, sounds, expressions and even whole documents. Import and Export can often deduce the appropriate format for data simply by looking at the extension of the file name for the file in which the data is being stored. "Exporting Graphics and Sounds" and "Importing and Exporting Files" discuss in more detail how Import and Export work. Note that you can also use Import and Export to manipulate raw files of binary data.
