> 1. I was testing the sample solution and when I enabled "-a" the output of the program still showed that it was skipping the "." and ".." directories - is this incorrect or is my understanding of the project requirements wrong?

> 2. What is meant to happen synchronising with both -a and -r enabled (and -n option not enabled). My first thought is that the syncing would recursively "enter" and synchronise the ".." directories > i.e. sync .., ../.., ../../.. etc. (in which case the whole computer will be synced!!!). However, from checking ls -a -R, it appears that the ".." directory isn't "entered"/scanned when -an and -r are both provided. Just wanted to ask for some clarity on this - given that I can't test this using the sample solution (as the zip file we provide would only be the top-level directory and wouldn't provide the file structure ".."?)
