I have just purchased and am trying to understand the system. I have already uploaded all folders to gdrive and now want to keep both systems in sync with each other. I will need two-way sync as I use multiple computers. On all computers I have a Nextcloud folder which contains documents etc and two other folders Photos and Videos.
I know I need to select selective sync but will it recognise folders and files already on the system and can I use two-way sync and selective sync please? Also I use a separate drive on the computers and keep the boot drive for the operating system only.
Thanks for the help.
