# Can I open online-only iCloud files without an internet connection?

No. An online-only file has to download before it opens, so it needs a connection to iCloud. Files that are already downloaded open normally offline.

To make sure files are there when you're offline:

1. Before you go, open the files or folders you'll need so they download.
2. Or right-click a folder in Finder and choose **Keep Downloaded** (available in recent versions of macOS), so macOS keeps it local.
3. Avoid running **Run Tuhi** just before a trip — its cloud step can make large downloaded files online-only.

When you're back online, anything you edited offline syncs up to iCloud as usual.
