Can sync all the file at once?
(ie.
Download all the changes requires first at destination (server sub), after all download complete, then merge all in once same time?
Reason: the game cant run (crashed) while sync running (sync file by file) .
At lease update in once , will reduce the crashed time possibility
Yeah, you cannot do that, as Syncthing operates on a per-file basis. This is one of the reasons why Syncthing isn’t recommended to be used for things like Git repositories and such, where all files need to be synced and up-to-date in order to remain functional.
