Tried the prescribed solution from @tflidd and it did not work, files were re-downloaded. No hidden files were missed in the copy to the new destination. Running ownCloud X sync client on windows 7 ultimate. There's 33gb of content on the remote server, so redownloading is not a viable option because multiple machines need the local folder moved to a secondary drive. Is there some other file at play on remembering the synced files than the .cfg file? I was able to revert the changes and files were not redownloaded.
Also server load and user's ISP usage limit usage, when onboarding new users that are geographically nearby, could be dramatically reduced if the current sync could be placed on their machine from an up to date machine, config files manually edited, and sync opened to only have incremental updates come in.
