With the popularity of computers and the development of the Internet, books have sublimated to another form, that is, e-books! Although e-books are not as easy to carry and read as books in daily life, they have many advantages such as low cost, simple production, convenient circulation and powerful functions.

Everyone should be familiar with e-books. Many novels, abstracts, materials or tutorials on the Internet are spread in the form of e-books. Compared with other media such as html pages, e-books can be read, stored and communicated better, which greatly facilitates our study and work.

Simply put, an e-book is an e-book that packages the original html, txt, doc and picture files into an independent executable file. There are many formats, such as EXE format, CHM format, HLP format, PDF format, LIT format, WDL format and so on. Some of these formats can only be opened and read by special software, but generally speaking, exe format and CHM format that can be directly run are the most widely used, and the e-books we make are all in EXE format.
