What are these folder options in the settings>folders>folder mode section?

In the settings folder, there are folder options for "preset collection folders", hyphenation folders" and PPD File Folders. Could someone elaborate on what they are for? I was looking in the references but did not find them. Thanks!

@Boldline In order of appearance:

• Preset Collections these are folders containing *.preset (VS) files, you can add these and presets will be scanned from there.
• Hyphenation custom hyphenation dictionary files.
• PPD File - Postscript Printer Definition files for VS Postscript printing (not with the host system driver).
