Macro is closing wrong workbook before going to the next workbook

I run most of my macros out of a file called "Personal.XLS" and I have this bit of code at the end of this particular macro which is closing personal.xls instead of the active file it is working on. It is set up on a loop and it should go to the next file in the directory but since it closes the file I run the macro from, the macro stops immediately.

It appears that it believes "ThisWorkbook.Close" is referring to the file from which the macro is initiated.

 
     'Opens ALL files in a folder, manipulates then saves as Excel
Dim fName As String

'Path with the files to convert
    ChDir "C:\My Documents\Excel Files"
'Create a list of the files in that folder
    fName = Dir("*")

'Open files one at a time to process them
    Do While Len(fName) > 0
    'Open file
        Workbooks.OpenText Filename:=fName, Origin:=437, StartRow:=1, DataType:=xlDelimited, TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, Semicolon:=False, _
            Comma:=True, Space:=False, Other:=False, FieldInfo:=Array(Array(1, 1), Array(2, 1), Array(3, 1), Array(4, 1), Array(5, 1), Array(6, 1), Array(7, 1), Array(8, 3), _
            Array(9, 1), Array(10, 1), Array(11, 1), Array(12, 1), Array(13, 1), Array(14, 1), Array(15, 3), Array(16, 1), Array(17, 1), Array(18, 1), Array(19, 1), Array(20, 1), _
            Array(21, 1), Array(22, 1), Array(23, 1), Array(24, 1), Array(25, 1), Array(26, 1), Array(27, 1), Array(28, 1), Array(29, 1), Array(30, 1), Array(31, 1), Array(32, 1), _
            Array(33, 1), Array(34, 3), Array(35, 1), Array(36, 1), Array(37, 1), Array(38, 1), Array(39, 1)), TrailingMinusNumbers:=True
        'Date format columns
            Range("H:H,O:O,AH:AH").NumberFormat = "m/d/yyyy"
        'your further code here
        
        'Save to same directory as Excel file with same name
            ActiveWorkbook.SaveAs Filename:=fName, FileFormat:=xlNormal, CreateBackup:=False
        'Get next filename
            fName = Dir
        'Close current file before moving on
            ThisWorkbook.Close
    Loop
    
MsgBox "Complete"
End Sub

I need the macro to close the file its working on and move to the next file in the dir.

Thanks!

ActiveWorkbook.Close
