OpenOffice.org uses its own file format. The files end with an .sxc, .sxw, or .sxi file extension, depending on whether they've been saved by Calc, Writer, or Impress, respectively. The OpenOffice.org format is the best choice when you're saving documents that you are likely to further edit within OpenOffice.org. However, if you wish to share files with colleagues who aren't running SUSE Linux or OpenOffice.org, the solution is to save the files as Microsoft Office files. To save in this format, just choose it from the Save As drop-down list in the Save As dialog box.
Alternatively, you might wish to save the file in one of the other file formats offered in the Save As drop-down list. However, saving files in an alternative format might result in the loss of some document components or formatting. For example, saving a Writer document as a simple text file (.txt) will lead to the loss of all of the formatting, as well as any of the original file's embedded objects, such as pictures.
To avoid losing document components or formatting, you might choose to output your OpenOffice.org files as PDF files, which can be read by the Adobe Acrobat viewer. The benefit of this approach is that a complete facsimile of your document will be made available, with all the necessary fonts and on-screen elements included within the PDF file. The drawback is that PDF files cannot be loaded into OpenOffice.org for further editing, so you should always save an additional copy of the file in the native OpenOffice.org format. To save any file as a PDF throughout the suite, select File ® Export As PDF. Then choose PDF in the File Format drop-down box, as shown in Figure 23-5.
