How does dedecms make a single page generated in a specified folder

When generating a single page, if you can generate different pages in the same folder, this can also make the file directory clearer, so you only need to change the settings in the background when generating a single page.
1. Column management>Change>File save directory Change all the columns that need to be put together to the same directory, and modify the name of the default page at the same time, this is to prevent page generation from being repeated
2. Find "System"-"System Basics" in the DEDE background Parameter"-"Core Settings", select "Column URL use directory name (default page is not displayed, that is, /a/abc/ form)" is "No".
