What kind of file is chm?

Compile your HTML page

CHM file is a "compiled HTML file" and an upgraded version of Microsoft Help file. hlp。 It uses open HTML to make help files more exciting and practical. More and more e-books are in CHM format, but few people know its application on the home page. Because CHM is the same as IE browser, IE can directly access the files contained in CHM files without opening a help window. For example, typing "MK: @ msitstore: c: \ Windows \ Help \ Windows.chm::/default.htm" in the Run column of Win98 (the default installation directory) will open the Windows Help system in the browser.

Let's analyze the above address: "mk:@MSITStore:" just like "yahoo.com". Give it a try!

4. Speed up the visit. If one of your columns is a CHM file, your visitors will be pleasantly surprised to find that, except that the first visit is a little slow, the subsequent visits will be the same as the website on the hard disk. In fact, after the first visit, CHM files are downloaded to IE's cache, and the subsequent visit is simply to read the hard disk, which will make visitors feel that your website is very stable.

There is nothing perfect in the world, and the CHM file format also has disadvantages: even if only one of the files contained in the CHM file is accessed, IE will download the whole CHM file, which leads to the slow speed of visitors' first visit. At present, there are only two solutions: one is to divide the content and use smaller CHM files (it is recommended not to exceed 50KB to take care of dialing friends), such as one CHM file for each column or topic; The second is to pre-download the CHM file of the previous page.

Second, make CHM files.

As for the tools for making CHM files, you can use Microsoft's HTMLHelpWorkshop (hereinafter referred to as HHW) or "Guohua Software Studio's eTextWizard (hereinafter referred to as EW).
