When using rclone rc core/stats, it shows only how much has been transferred but no information of total size.
Have looked up document about rclone rc (the document is messed up since here possibly because Markdown problem) but there are too many available parameters (do not want to try it one by one )
cannot get total size using rclone rc sad. How dose the default output calculate it? Dose it run rclone size src: and rclone size dst: then calculate the gaps?
You could just check the code if you are comfortable reading that (go isn't the most cryptic of languages).
That is also right there on github, since you are looking for a very spesific function in the RC here it shouldn't be too hard to identify where in the code that is I imagine.
