Splitting the file will automatically update all links and references that

pointed into the bottom half of the file and will open the newly split file in
|

an editor. If you want to repeatedly split a file, you can do that, and then

use the bulk renaming facility of the Files Browser, described above, to give

the split off files sensible names.

|

You can also split a single HTML file at multiple locations automatically, by
|
||||
right clicking inside the file in the editor and choosing :guilabel:`Split at
|
||||
multiple locations`. This will allow you to easily split a large file at all
|

heading tags or all tags having a certain class and so on.
