- &gnum; stores its information by creating files and re-opening
- these files during a future session. Saving information to files
- also allows a user to send the information to others.

- The default file format for &gnum; is based on the eXtensible
- Markup Language (XML). By default, files are saved as text files,
- consisting of XML, which are then compressed using the library of
- the <application>gzip</application> program. The extension for
- &gnum; files is <literal>.gnumeric</literal> on platforms which
- support file extensions of any size, <literal>.gnum</literal> for
- systems which restrict extensions to four letters, or
- <literal>.gnm</literal> for systems which restrict extensions to
- three letters.

- &gnum; can also open or save files in a number of other file
- formats. The project prides itself for the work reverse
- engineering and supporting the file formats used by Microsoft
- Excel. &gnum; can use the Excel file format as if it were the
- native file format, meaning that &gnum; can store and retrieve
- essentially every aspect of a worksheet using the Excel
- format. Similarly, &gnum; supports the OASIS standard Open Office
- XML file format as if it were the native format.

- &gnum; cannot delete files from the file system. &gnum; can open
- existing files and create new files but cannot delete files once
- they are created. Files can be deleted using a file browser such
- as <application>Nautilus</application> on the GNOME desktop or
- using the command-line program <application>rm</application>.

- This chapter discusses working with actual files. It is also
- possible to import data into &gnum; using the clipboard by
- copying either text or html table information in another program
- and then pasting the resulting data into a worksheet. See <xref
- linkend="sect-movecopy-xclipboard"/> for details.

- Text files are often used to store data, using many different
- systems to structure the data such as using commas, tabs or spaces
- to separate values. &gnum; features a flexible system that enables
- users to define exactly the structure of the text file to be
- opened or saved.

- &gnum; can be integrated with an email client to allow files to be
- sent directly as attachments to an electronic mail message.

- &gnum; also features a command-line tool called
- <application>ssconvert</application> to convert files between any
- of the file formats which it supports.
