I would like to access the file system.xml located in the parent directory of $Home. What can I do?

Use http get request: `https://127.0.0.1:80/fileservice/system.xml`

Sometimes the path is [https://127.0.0.1:5466/fileservice](https://127.0.0.1:5466/fileservice). How can I determine whether the port is 80 or something else?

For a virtual controller running on your local computer, you can check the port used by the process to do this (this is a powershell command)

`Get-NetTCPConnection -State Listen | Where-Object { $_.OwningProcess -in (Get-Process Vrchost64).Id } | Format-Table LocalAddress, LocalPort, OwningProcess`

You can get the response like:

```txt
LocalAddress LocalPort OwningProcess
------------ --------- -------------
:: 5466 11696
:: 80 13408
0.0.0.0 53777 11696
0.0.0.0 51683 13408

```

The localPort starting with the two colons (`::`) in front indicates the port that the virtual control cabinet is listening on.
