If you want to work on files with friends or colleagues, you can share individual files or create a shared folder to share a group of files. You can also pin files and folders so you can use them offline, and easily check the status of a download or shared file.
When you create a file on your PC and save it to the iCloud Drive folder, it also appears on your other devices. You can find documents that you’ve stored in iCloud in this folder. When you turn on iCloud Drive, iCloud for Windows creates an iCloud Drive folder in File Explorer.
