TBH, if what you want is to ALWAYS show the latest unofficial files that you have downloaded, that's what you should do also, instead of storing things in the unofficial directory. (This was suggested above by Magnus.)
It's actually a little more complicated. There is no "library" that LDView loads on the server. The library software creates a self contained MPD file of the part that has all the subparts/primitives included. Since the library knows the subpart tree and if a part is official or unofficial it changes how that MPD is constructed. If the part is official, it only uses official data. If the part is unofficial, it prioritizes unofficial files (e.g. part fixes) over official files.
None of this helps you Tom.
What I would suggest is use Travis's suggestion to prioritize unofficial over official parts and every on new LDraw release:
- Overwrite library with complete.zip
- Delete all your downloaded unofficial parts and either use the ldrawunf.zip or have LDView re-download the unofficial parts for you.
