I am a student so I have to download many PDF files and for that I needed an drive storage app which could store my data safely.As I know google is a very famous and genuine company so I went for the Google Drive and downloaded it. As I tried to open the drive it took about 10 minutes to open and after that I attached it with my Google account.But whenever I tried to download the files in my drive it rejected it and said that this format is not supported and after that by luck when something got download it was not opened properly and was problems jn changing the slides.
