, so all network addresses currently use slashes as delimiters.Windows uses a slash as a parameter identifier for a DOS command prompt, and in order to avoid confusion, a backslash is used as the path delimiter. Currently, the file browser on the Windows system uses a backslash as the path delimiter.Conclusion:1. The browser address bar URL using a slash;2. Use a backslash on the Windows file browser;3. The path that appears in the HTML URL () property must use a slash when the path specified is
