For editing very large documents (file size up to 300 MB) a special memory optimization is implemented on loading such a file so that the total memory allocated for the application is not exceeded. The minimum file size that enables this large file optimization can be configured with the option OptionsPreferencesEditorOpen/Save+Optimize loading in the Text page for files over (MB)

A temporary buffer file is created on disk so you should make sure that the available free disk space is at least double the size of the large file that you want to edit. For example <oXygen/> can load a 200 MB file using a minimum memory setting of 512 MB and at least 400 MB free disk space.
