Google gives every free account a shared 15GB pool that splits across Gmail, Drive, and Photos. When your Google storage gets full, most users open the Photos app and start deleting. But that move almost never works. The files eating your account rarely sit in your gallery at all. They hide inside parts of Google that the main storage screen ignores, and the biggest ones stay invisible unless you know exactly where to look. Real cleanup starts on a page Google never nudges you toward, and photos wait until the end.
