Will create a display with all different files from one directory to another
< indicates that a file only exists in the first file
> indicates that a file only exists in the second file
node diff.js drive:sub/dir drive2:sub/dirWill output dif between directories divided by subdirectory Will also create and return a tmp diff file that you can call directly using
node diff.js [tmpdifffile](no brackets)
You will need rclone setup and both your destinations configured
