If there are many web pages, only a few html pages such as index.html should be used in the root directory, and it is better to put the others in the corresponding subdirectories. If you must put it in the root directory, you must consider the name of the file. For a simple example, for example, if a website contains definitions of Chinese characters, the page corresponding to each definition is named as the code value of Chinese characters, so that documents can be found conveniently according to the code value. Or build a table to record the document name and the corresponding page content, which is convenient for later maintenance and change.
