A couple of usability questions that don&#x27;t appear to have been addressed in the video:<p>- on a Mac, if I press the spacebar to show the quick preview and start navigating down the list, will this trigger downloading of all the files?<p>- how are older files cached? Do we simply unselect devices to remove them locally? At least with Selective Sync, I can remove files eating up my hard drive (very important on devices with 128GB SSDs&#x2F;HDs or less). It&#x27;s much clearer in terms of what&#x27;s on disk and how to manage it with Selective Sync. With Project Infinite, I&#x27;m wondering how one would remove files locally without fully deleting the file across the Dropbox folder for every other team member.
