1. Open the Google Drive website (drive.google.com) and log in to your account.

2. Locate the file or folder that you want to rename in your Google Drive.

3. Right-click on the file or folder and select "Rename" from the dropdown menu.

4. Type in the new name for the file or folder and press "Enter" or click outside the text box to save the changes.
