If you want to delete files from your Google Drive account on an iPhone, there are a few different ways to go about it. The first option is to use the Google Drive app on your iPhone. Open the app and select the files you want to delete. Tap the three lines in the top left corner of the screen and select “Delete.” If you don’t have the Google Drive app, you can also delete files from your Google Drive account by using iTunes on your computer. Open iTunes and connect your iPhone to your computer. Click the “iPhone” tab in iTunes and select “Files & Folders.” Select “Google Drive” from the list of folders and click “Delete Files.” ..
