Sorry for wrong info I sent. The downloaded parts are not fzb nor are they fzpz parts.
They are all fzp parts.
If I import all the downloaded fzp parts into Fritzing it will probably over write all the original parts that came with Fritzing.
If they import and work it's great, but I am concerned that if they don't work how will I recover from the mess?
I will then have to reload Fritzing again from scratch.
Has anyone in the Fritzing usergroup updated their parts in Fritzing successfully?. If so, How?
