How to import e-books (pdf files) into ipad? First of all, if you want to read e-books (pdf files), you must install the software on the ipad (or ipod, iphone). There are two free softwares I am using, which feel good and free. One is "ibooks" and the other is "cloudreaders". For the installation and use of software, I won't say much here, and people who can use Apple system should know better. After installing the corresponding program, the most important thing is how to import the files from the computer into the ipad device. In fact, using itunes is also very simple. Open itunes, select the file option, and click Add File to Repository or Add Folder to Repository. The search scope selection box will appear. Please search according to the location of your document, and then double-click (or click Open). At this time, an item "Book" will appear in the database list in the left column of itunes. The cover of the pdf file you added will appear in the right column. At this point, the book is added to itunes. (In fact, this step is just like adding music material. Adding books to itunes is only half the task. Next, we will synchronize the books to the Apple device. Connect devices such as ipad to the computer, and click your device (ipad, ipod, iphone) under the left device in the connected itunes to open the interface of device synchronization. Select "Book" in the top option of the synchronization interface to enter the synchronization book interface. At this point, the book cover just added has been displayed in the interface. Select the "synchronize books" checkbox in the interface, and itunes will prompt "Are you sure you want to synchronize books?" Of course, click "Synchronize Books" in the prompt box. You can then choose whether to synchronize All Books or Selected Books. Of course, "Selected Books" requires you to discard some books that you don't want to sync to the ipad. (There is also a "Synchronize audio books" check box under "Synchronize books". If you have it, choose it. If you don't, don't worry. After that, click "Apply". Synchronize the selected related content, just like other materials. After the synchronization is completed, use the corresponding software to open the file and read it. In addition, if such information infringes your rights, please let us know and we will delete it in time. )
