Answer 1

这是浏览器安全限制，在现代浏览器中，您无法获得所选文件的完整客户端文件系统路径，也无法以编程方式设置路径...

Answer 2

Maybe for security reason, javascript doesn't allow this to happen. And if you come to think of it, Server side pages cannot access your local files. Not that I have a solution for your question.

Answer 3

Actually, there is some kind of solution.
Albeit, it will help only if you can run Electron desktop app on local machine: https://stackoverflow.com/a/59990858/9390914
