Whenever you make modifications to a document, it's a good idea to periodically save your work.

To save a document, select the save option from the file menu. You can use the “save as” command to save a copy of the file or the “Save all” option to save all open documents.

You can configure OpenOffice to automatically save your documents using the autosave feature. To configure this feature, select the tools menu, and then select options.

Next, expand the load/save item by clicking on the plus sign then select “General”.

In the “Save” section, make sure the “autosave” checkbox is checked. If you like, you can specify the number of minutes that OpenOffice will wait to automatically save the document.

If you want to be prompted before the automatic save happens, click the “prompt to save” checkbox. This will let you override or confirm the autosave action.

You can also have OpenOffice automatically create a backup of your file when it saves if you select the “always create backup copy” checkbox.

When you're finished click the OK button.
