[VBA] Check column if empty, fill in filename for multiple files

[stupideye]

Hello,

Looking for some help on a seemingly simple issue. I have some VBA code here that I've scrounged up from searching for a solution to my problem, but I've hit a wall with the final bit.

I'm trying to have this do:
1. Look in a folder
2. In each Excel file in the folder, open them, insert a empty column A
3. In every row that isn't blank in column B, put the filename in column A
4. The filename of these files is for example "Sales January 1, 2020", I'm looking to only keep the date part of it.. I know how to do that with a formula, but not in VBA

The following code does everything except for 3 and 4. Any advice on this one?

Thank you in advance!

Sub FillDate()
    Dim MyPath As String, FilesInPath As String
    Dim MyFiles() As String, Fnum As Long
    Dim mybook As Workbook
    Dim CalcMode As Long
    Dim sh As Worksheet
    Dim ErrorYes As Boolean


    'Fill in the path\folder where the files are
    MyPath = "E:\Path1\2020\Path2\Database\Path3\"

    'Add a slash at the end if the user forget it
    If Right(MyPath, 1) <> "\" Then
        MyPath = MyPath & "\"
    End If

    'If there are no Excel files in the folder exit the sub
    FilesInPath = Dir(MyPath & "*.xl*")
    If FilesInPath = "" Then
        MsgBox "No files found"
        Exit Sub
    End If

    'Fill the array(myFiles)with the list of Excel files in the folder
    Fnum = 0
    Do While FilesInPath <> ""
        Fnum = Fnum + 1
        ReDim Preserve MyFiles(1 To Fnum)
        MyFiles(Fnum) = FilesInPath
        FilesInPath = Dir()
    Loop

    'Change ScreenUpdating, Calculation and EnableEvents
    With Application
        CalcMode = .Calculation
        .Calculation = xlCalculationManual
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    'Loop through all files in the array(myFiles)
    If Fnum > 0 Then
        For Fnum = LBound(MyFiles) To UBound(MyFiles)
            Set mybook = Nothing
            On Error Resume Next
            Set mybook = Workbooks.Open(MyPath & MyFiles(Fnum))
            On Error GoTo 0

            If Not mybook Is Nothing Then


                'Change cell value(s) in one worksheet in mybook
                On Error Resume Next
                With mybook.Worksheets(1)
                    If .ProtectContents = False Then
                    'Insert new column
                        Columns("A:A").Insert Shift:=xlToRight, _
                        CopyOrigin:=xlFormatFromLeftOrAbove             
                    Else
                        ErrorYes = True
                      
                    End If
                End With


                If Err.Number > 0 Then
                    ErrorYes = True
                    Err.Clear
                    'Close mybook without saving
                    mybook.Close savechanges:=False
                Else
                    'Save and close mybook
                    mybook.Close savechanges:=True
                End If
                On Error GoTo 0
            Else
                'Not possible to open the workbook
                ErrorYes = True
            End If

        Next Fnum
    End If

    If ErrorYes = True Then
        MsgBox "There are problems in one or more files, possible problem:" _
             & vbNewLine & "protected workbook/sheet or a sheet/range that not exist"
    End If

    'Restore ScreenUpdating, Calculation and EnableEvents
    With Application
        .ScreenUpdating = True
        .EnableEvents = True
        .Calculation = CalcMode
    End With
End Sub

What it should do (if the filename was "Sales January 1, 2020.xls")(italic text is what the VBA would fill in):

Col A	Col B	Col C
January 1, 2020	1234	$10
January 1, 2020	567	$12
