First, visit the Google Storage Manager website in your Windows 10, Mac, or Linux browser and sign in to your Google account.

Scroll down until you reach the “Large items” section. Here, you’ll find separate boxes with the largest documents in your Gmail, Google Drive, and Google Photos.

Click the “Review and Clear” or “Review and Free Up” button under any of these tabs to browse a list of the largest files you have stored on that particular service.

On the following screen, you can click on any file to preview it. If you want to delete one or more of the items listed, first, select each item you want to delete by clicking the circle in the upper-left corner of the thumbnail (until it has a check mark). Then, click the trash can icon in the upper-right corner of the window.

Please note that files deleted from here will not be available in the “Bin” or “Trash” folder in Google Drive. They will be permanently removed from your account.

In the confirmation prompt that appears, check the box “I understand that once I delete the files, they cannot be recovered from the bin” and then click “Permanently Delete”.

Depending on the total size, Google will take a few minutes to delete the selected files.
If you're frequently running out of space on Google services, you might want to upgrade your storage with Google One. Good luck!
