How do I open .icloud files? I'm saving data to iCloud in my app using iCloud Documents capability, however I'm not using the Documents folder, instead I'm hiding my files in another folder i.e. User'siCloudContainer/MyFolder.

I've uploaded some .plist files to this folder but when I receive them using another device they've been given a .icloud extension. What does this mean and how can I get my original .plist files?

EDIT: It seems that these files have been wrapped by NSFileWrapper during cloud synchronisation.
The answer as I have now discovered is that .icloud files are the metadata that precedes the full file being downloaded to a device.
