That is 100% correct!
If you were to grep the rclone source for NewCheckingTransfer you'll find all the places that these are used. (What a confusing name!)
Checkers are used in rclone to mean any process affecting a file/object which isn't a transfer, so could be
- hashing
- reading modtimes
- deleting
- renaming
Amongst others.
However these are all printed in the stats as
The easiest way to fix this would be to think of another word for checking like in-use or working.
Slightly harder would be for each type of thing to get its own word, so deleting, renaming, hashing, reading modtime but that would be a lot more usable.
What do you think?
