Simply, open Google Drive, then after that drag the PSD file to your Google Drive. Google Drive is a beautiful and easy option if you just want to view the image inside the PSD file. Just like WMA is the propriety of Microsoft, but you can play a WMA audio file with most music players, similarly, PSD is owned by Adobe, but other programs can also open (and sometimes edit) a PSD file. This PSD file contains all your images, layers, functions like color correction, etc store in original quality. When you save an image in Photoshop, the default format is PSD (short for Photoshop document).
