Move to question

[Peter Blomberg]

When a part number is updated, a move to file is created for the old number. Why does the new part use the subfiles from the old part number?

e.g. https://library.ldraw.org/parts/49972

[Orion Pobursky]

Mostly to reduce clutter and avoid unnecessary emptying of files (since non-parts folder files don't need move-to's).
