Note

If the spreadsheet has been previously saved, then saving it

using the Save (or Save All) command will overwrite an

existing copy. However, you can save the spreadsheet in a

different location or with a different name by selecting File >

Save As.

Password protection

To protect an entire document from being viewable without a

password, use the option on the Save As dialog to enter a password.

This option is only available for files saved in OpenDocument formats

or the older OpenOffice.org 1.x formats.

On the Save As dialog, select the Save with password option, and

then click Save. You will be prompted to type the same password in

two fields. If the passwords match, the OK button becomes active.

Click OK to save the document as password-protected. If the

passwords do not match, you will be prompted to type the password

again.

OOo uses a very strong encryption mechanism that makes it almost

impossible to recover the contents of a document in case you lose the

password.

Saving a document automatically

You can choose to have Calc save your spreadsheet automatically at

regular intervals. Automatic saving, like manual saving, overwrites the

last saved state of the file. To set up automatic file saving:

1) Choose Tools > Options > Load/Save > General.

2) Click on Save AutoRecovery information every. This enables

the box to set the interval. The default value is 15 minutes. Enter

the value you want by typing it or by pressing the up or down

arrow keys.

Saving as a Microsoft Excel document

If you need to exchange files with users of Microsoft Excel, they may

not know how to open and save *.ods files. Only Microsoft Excel 2007

with Service Pack 2 (SP2) can do this. Users of Microsoft Excel 2007,

2003, XP, and 2000 can also download and install a free

OpenDocument Format (ODF) plugin from Sun Microsystems.
