What happened?

When pressing @ plus a file name in a sub directory, on Windows, the path suggested for auto complete use "\" instead of "/":

This cause the ReadManyFiles to fail:

Manually replacing "\" with "/" would allow ReadManyFiles to run successfully:

Using "\" like currently would also cause a model understanding issue if the file in the sub directory contain space. For example, if I change the "test.txt" above to "test test.txt", press "@test.txt" then tab to auto complete the path, this would be the result:

As you can see, this time ReadFile did not run.

What did you expect to happen?

On Windows, @ with a file name in a sub directory should use / for path, since \ is used for escaping. This cause ReadManyFile to fail.
