Rclone can't flatten the directory structure like that at the moment.
Are you doing the sync over and over or just a once off?
What you could do is sync to the Jan/18Jan/19 directory structure then write a little script to hardlink the files into the destination directory. This won't use any more disk space and will allow you to repeat your sync over and over again.
A script to flatten the files would be
find /path/to/source/files -type f -exec ln -v \{\} /path/to/dest/ \;
my problem was that if I sync to one major directory and have like 5-6 syncs to one main directory each sync will delete the other ones work since their source is different
like sync /picture/jan/18 to pics/
sync pictures/jan/19 to pics/
I feel ill just use copy instead
I guess I was over complicating it
the deletions would be rare and can be handled manually
Thank you so much I dont want to take more of your time
