How can I edit files directly from myCloud? (Android)
Cynthia 3 months ago Update
If you want to edit and save a file directly from myCloud, open the “Files” section of the myCloud application and navigate to the file you want to edit.
Click on the context menu (the three dots) and select “Edit”.
You can now choose which application you want to edit the file with. Any changes you make are transferred directly to myCloud upon saving.
