E-books must be downloaded in the form of electronic documents through special reading software to any general platform or books on readers that can store a large number of digital reading data, which is a substitute for traditional paper books.

E-books can be divided into TXT file format and PDF file format.

TXT file format This is a popular e-book file format, which is favored by many people, and there are also the most tools to make this format. Its biggest feature is that it is easy to read and do, and the e-books produced are also pretty good. This format of e-books is embedded with reading software, which can be read without installing a special reader, and has no high requirements for the running environment.

PDF file format has nothing to do with the operating system platform, which makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. More and more e-books, product descriptions, company announcements, online materials and e-mails begin to use PDF files. At present, PDF file has become the de facto industrial standard of digital information.
