Transferring ownership of a Google Drive file or folder is very easy to do. There are three types of user in Google Drive - Owners, Editors, and Viewers. These are determined by the person who owns the files and folders. As the Owner of files and folders, you can quickly and easily change the ownership to another person.
Step 1: Go to Google Drive and select the folder you wish to change the ownership of.
Step 2: Click on the drop-down menu and click Share.
Step 3: The person you want to transfer the folder to must first have access to the folder. Enter their email address into the box to share this. Make sure you click Send, otherwise you won't be able to change the preferences for them.
Step 4: Once the person has access, click on Advanced, in the bottom right hand corner of the box. This will expand the area to share with others, and provide more options. Click on the drop-down menu to the right of the person's name and change their permissions from "Can organise, add and edit" to "Is the owner".
Step 5: Save Changes.
Step 6: Confirm the change of ownership by clicking Yes.
