To check a downloaded book, first go to the folder where your downloads are saved—usually called “Downloads” in your phone or computer. If you can’t find it, use the File Manager or Search bar and type the book’s name. If it’s a PDF or eBook, open it using apps like Adobe Reader, Google Play Books, or any PDF/eBook reader. Make sure the file is fully downloaded and not broken. Check the file size and format to be sure.
