Does Run Tuhi make my iCloud files online-only?
Short answer: Yes. When cloud folders like iCloud Drive are on your Mac, Run Tuhi includes a Keeping cloud files online-only step that frees large downloaded files. Nothing is deleted — files stay in iCloud and download when opened.
Yes, when you have cloud folders such as iCloud Drive on your Mac, Run Tuhi includes a step called Keeping cloud files online-only. It looks for large downloaded files in your cloud folders and makes them online-only, then reports how much space that freed.
Like every online-only step in Storage Studio, it never deletes anything: the files stay in iCloud and download again when you open them. Files that aren't using local space are left alone.
If you'd rather keep everything downloaded, don't run it right before you go offline. To free just one big iCloud file, use Free up in Storage Profile's Biggest space-users list instead. See Tuhi & Free Up Space.
