In answer to Norm's query,
"...to copy from one cloud to another it goes through Places. Is that the local copy of Places, or is there a Cloud >> PlacesCloud >> Cloud transfer that takes place without having to go down to the local computer?"
"As to copying, Places is the "conduit" between all connections for when you want to transfer data from one Place to another. Nothing however is stored locally once the transfer is complete."
I'm curious about whether Places's cloud "conduit" servers store cloud information that passes through it. And, if Places is run from a pendrive, are all temp files (even if subsequently deleted) that are generated locally written to the pendrive rather than the host machine?
Files that are transferred from A to B are completely deleted and not stored in any location Places is being used on even when being launched from a USB drive.
