Always create backup copy
Saves the previous version of a document as a backup copy whenever you save a document.
Every time LibreOffice creates a backup copy, the previous backup copy is replaced. The
backup copy gets the extension .BAK.
Save AutoRecovery information every __ Minutes

AutoRecovery in LibreOffice saves the information needed to restore all open documents in
case of a crash. If you have this option set, recovering your document after a system crash will
Save URLs relative to file system / internet
Use this option to select the default for relative addressing of URLs in the file system and on
the Internet. Relative addressing is only possible if the source document and the referenced
document are both on the same drive.
A relative address always starts from the directory in which the current document is located. In
contrast, absolute addressing always starts from a root directory. The following table
demonstrates the difference in syntax between relative and absolute referencing:
If you choose to save relatively, the references to embedded graphics or other objects in your
document will be saved relative to the location in the file system. In this case, it does not matter
where the referenced directory structure is recorded. The files will be found regardless of
location, as long as the reference remains on the same drive or volume. This is important if you
want to make the document available to other computers that may have a completely different
directory structure, drive or volume names. It is also recommended to save relatively if you
want to create a directory structure on an Internet server.
If you prefer absolute saving, all references to other files will also be defined as absolute,
based on the respective drive, volume or root directory. The advantage is that the document
containing the references can be moved to other directories or folders, and the references
Default file format and ODF settings
ODF format version. LibreOffice by default saves documents in OpenDocument Format
(ODF) version 1.2 Extended. While this allows for improved functionality, there may be
backwards compatibility issues. When a file saved in ODF 1.2 Extended is opened in an editor
that uses earlier versions of ODF (1.0/1.1), some of the advanced features may be lost. Two
notable examples are cross-references to headings and the formatting of numbered lists. If you
plan to share documents with people who use editors that use older versions of ODF, you may
wish to save the document using ODF version 1.0/1.1.
Size optimization for ODF format. LibreOffice documents are XML files. When you select this
option, LibreOffice writes the XML data without indents and line breaks. If you want to be able
to read the XML files in a text editor in a structured form, deselect this option.
Document type. If you routinely share documents with users of Microsoft Office, you might
want to change the Always save as attribute for documents to one of the Microsoft Office
formats. Current versions of Microsoft Word can open ODT files, so this may no longer be
