Copy, Rename and validate multiple excel files

Hi All, Been scratching around for the last 5 days to find something that works for multiple files. Many a late night/early hours of the morning unsuccessfully piecing together/coding to get a result.
Thanks in advance.

The following code is from get-digital-help.com/copyrename-a-file-excel-vba written by Oscar
I'd really like each row to look at the source path, source file name, destination path and destination file:

For each row:
Column A list the source path
Column B lists the source file name
Column C lists to destination path
Column D lists the new file name

Column E writes "Success" or "Fail" validation.
- if file name already exists in destination, then "Fail"
- If source file doesn't exist, then "Fail"


Nice to have/completely optional!!!
Check if source file column A&B exists, = True or False in column F. Where True, then proceed with copy and rename.
If destination file already exist, the fail and column F = duplicate

Sub CopyRenameFile()

'Dimension variables and declare data types
Dim src As String, dst As String, fl As String
Dim rfl As String

'Save source directory specified in cell A2 to variable src
src = Range("A2")

'Save destination directory specified in cell C2 to variable dst
dst = Range("C2")

'Save file name specified in cell B2 to variable fl
fl = Range("B2")

'Save new file name specified in cell D2 to variable rfl
rfl = Range("D2")

'Enable error handling
On Error Resume Next

'Copy file based on variables src and fl to destination folder based on variable dst and name file based on value in rfl
FileCopy src & "\" & fl, dst & "\" & rfl

'Check if an error has occurred
If Err.Number <> 0 Then

'Show error using message box
    MsgBox "Copy error: " & src & "\" & rfl
End If

'Disable error handling
On Error GoTo 0

End Sub
