I have been doing some trial and error between my PC and laptop and found the best way to deal with created or downloaded parts was to create a networked library accessible by both of my machines. (I tried putting all of the libraries over the network but that ran unbelievably slow when I tried to search for parts).
I love the new ModelSource integration into DesignSpark though it always downloads the part to a relevant local folder - which is great for most cases but not mine. I can't find a way to set a default download location... either a set local library (that I could sync over my network) or an external library (NAS based).
Does anyone know how to do this? My current work-around was to create a library on the network then download the part, search for the part and copy to the networked library - which is a real pain but it does work.
First entry in the Libraries was set to the networked folder, download as per normal and it created a 'DownloadedLibraries' folder inside the existing folder. Add this folder to my libraries on the laptop and job done :)
Not the best way but it works without me having to do extra work!
DesignSpark PCB is using the DownloadedLibraires folder to ensure the ModelSOurce files are separated from other library files. You will find a UserLibraries folder which is intended to store any files downloaded from ModelSource but modified/adjusted by a user.
You are right networked use is not required by most users but it is something we are looking into as more and more users want to collaborate with other co-workers or colleagues
