Giving a relative path to find a file

I have been working on this program to see if it can find a file in my computer.
What the user has to do is run the the program and in an empty text field type the file name with no extensions required. The file name is numeric and then I change it to string to search for the file.

Here is what I got:

    /// <summary>
    /// This object will be used to call the OpenFiles function to search for user files
    /// </summary>
    BrowseUserData FileBrowser;
public string s_xmlFileToOpen = string.Empty;

    void Awake()
    {
        FileBrowser = GameObject.FindGameObjectWithTag("MainCamera").GetComponent<BrowseUserData>();
    }
    void OnGUI()
    {
        //we draw our main GUI backdrop where the rest of the GUI elements will be drawn
        GUI.Box(r_GUIBackdrop, "Playback Application");
        //we draw the label in the scene
        GUIManager.DrawLabel(r_GUIBackdrop, r_lbl_UserSearchMsg, "Please enter the user ID");
        //we draw the text field in the scene
        GUIManager.DrawTextField(r_GUIBackdrop, r_txt_UserSearchField, ref i_filePath, 4);
        s_xmlFileToOpen = "../SavedData/"+i_filePath.ToString() +".xml";
        //draw the button in the scene
        if (GUIManager.DrawButton(r_GUIBackdrop, r_btn_LoadUserFile, "Load"))
        {
            FileBrowser.OpenUserFiles(s_xmlFileToOpen);
        }
    }

Next, in my other class I check if the file exists or not:

/// <summary>
    /// This function searches for the user files  
    /// </summary>
    /// <param name="userFiles"></param>
    public void OpenUserFiles(String xmlFile)
    {
        if (File.Exists(xmlFile))
        {
            Debug.Log("Found Them");
        }
        else
            Debug.LogError("Failed to find correct file paths");
    }

Can anyone help me find out why I my code is not finding my file? Thanks in advance!

Maybe xmlFile contains relative path?

Try outputing Directory.GetCurrentDirectory Method (System.IO) | Microsoft Learn , I think you’re in the wrong directory.
