I’m trying to setup Syncthing between two machines, and my goal is to share a single very large folder (over 1TB). As I don’t want machine #2 to re-download everything from scratch, I made an initial copy of the folder using an USB drive and put all the files in place “offline”.
Will it work? More explicitly: does Syncthing scan the local folder first, and only then attempt to download what’s missing?
Additional question: I assume that Syncthing will check if a local file matches by checksum. What would happen, for example, if the local file is identical to the remote but the file date is different?
