It was very informative and helpful. I only have one follow-up question. I followed your advice on NOCOW for virtualbox images and torrents like so: chattr -v /home/juha/VirtualBox\ VMs/ chattr -RC /home/juha/Downloads/torrent/#unfinished As you can see, i used the recursive flag. However, I do not know whether this will automatically apply to files that will be created in the future in subfolders that do not yet exist. Also, how can I confirm whether a file/folder has a NOCOW attribute set on it?
