Google Drive - Personal Cloud Storage & File Sharing Platform

The total storage is actually shared with other Google services, like Gmail and Google Photos. If you don't use these services, you can utilize almost all the space for Google Drive alone. Keep in mind that your Google Docs, Sheets, Slides, Drawings, Forms, Photos, Gmail, and Jamboard files all compete for that 15 GB free allotment.

Desktop users can install a sync client, which supports folder and file uploads. There's also a mobile app that can send photos and videos to your account.
