This looks like a typical %USERPROFILE% folder in Windows, so I need to ask this question. Are you absolutely sure that these are the only files and folders that you want to ignore?
I am asking, because in that folder there are many more hidden and system files and folders, which may not be visible in the Explorer by default. However, Syncthing does not care whether a folder is “hidden” or “system” in Windows, and will go through all of them.
Do you really want to sync all of these?
If yes, then please ignore this post, but if that is not the case, and the only folders that you really want to synchronise are:
then I would suggest adding to your .stignore the following:
!/Desktop
!/Documents
!/Downloads
!/Music
!/Pictures
!/Videos
*
This way, Syncthing will sync only the specifically listed folders, and ignore everything else.
