Retire MPD

[Orion Pobursky]

If I remember correctly there was confusion among the casual user that a ldr file could not only contain dat files, so parts, but also other ldr files called submodels. From an organisational point of view it should be handled like this:

dat - parts
ldr - single model
mpd - multiple models

Our customer is not the handful of people who regularly post here on the forum. Our customer is the casual user who never even looks at the forum. The fact that Weber had a few question this matter hints at a larger issue. From their standpoint the difference is confusing especially since Some programs don't save with the MPD extension by default. 

Confusion is bad. Simplification is good.
