Excluded array paths have slashes not pipes
Don't add deleted files to diffPaths array also, keep them seperate
Can't use a for loop to add deleted files, only adds last reference as
happens before a tickover
Instead use a setInterval as a loop, with k as the counter instead of j
to avoid confusion
Check if it's not excluded dir/file as an outer if statement, with path
fix for root
3 cases set up for adding deleted dirs/files in a sub-dir, plus folder
or file in the root
Clear the interval when finished looping
