Error when copying files to an existing folder - vba

Question

I am writing some code that prompts the user to add a folder name, then copies all the files on the CD drive (D:) to C:\Example\ & FolderName if it doesn't already exist.
The code works until I try to copy files to a folder that already exists then I get a Run-time error 70: Permission Denied. Any help would be greatly appreciated.
Public Sub CopyFiles()
Dim FSO As Object
Dim FromPath As String
Dim ToPath As String
Dim FileExt As String
Dim FNames As String
Dim FolderName As String
FolderName = InputBox(Prompt:="Your folder name", Title:="Folder Name", default:="Folder Name here")
If Dir("C:\Example\" & FolderName & "\", vbDirectory) = "" Then
MkDir "C:\Example\" & FolderName
Else
End If
FromPath = "D:\"
ToPath = "C:\Example\" & FolderName & "\"
FileExt = "*.flac*"
If Right(FromPath, 1) <> "\" Then
FromPath = FromPath & "\"
End If
FNames = Dir(FromPath & FileExt)
If Len(FNames) = 0 Then
MsgBox "No files in " & FromPath
Exit Sub
End If
Set FSO = CreateObject("scripting.filesystemobject")
FSO.CopyFile Source:=FromPath & FileExt, Destination:=ToPath
End Sub

The problem is not that the folder exists. The problem is that you are trying to copy files and overwrite them
Overwriting is usually not a problem but fails if the files in the destination folder have Read Only Attributes. You can read more about it in this MSDN Article
What happened was when you first copied the files from the CD Drive, the file which where copied retained the Read Only Property. You can check that by Right Clicking on the File and checking their properties.
To overcome this problem, you need to reset the file attributes or delete the files in that folder.
To delete, you can simply use
On Error Resume Next
Kill "C:\MyFolder\*.*"
On Error GoTo 0
To change the attributes, you have to loop through the file and check if their property is read only. You can do that by
If fso.GetFile(Dest_File).Attributes And 1 Then
and to reset it, you have to use
fso.GetFile(Dest_File).Attributes = fso.GetFile(Dest_File).Attributes - 1
Once you do that you will be able to copy the files across.

As Siddharth mentioned, the error occurs because the code is trying to overwrite existing files. So, if you don't want to overwrite the files, you can simply add a If Error Resume Next. The solution code I am using is below:
Public Sub CopyFiles()
Dim FSO As Object
Dim FromPath As String
Dim ToPath As String
Dim FileExt As String
Dim FNames As String
Dim FolderName As String
FolderName = InputBox(Prompt:="Your folder name", Title:="Folder Name", default:="Folder Name here")
If Dir("C:\Example\" & FolderName & "\", vbDirectory) = "" Then
MkDir "C:\Example\" & FolderName
Else
End If
FromPath = "D:\"
ToPath = "C:\Example\" & FolderName & "\"
FileExt = "*.flac*"
If Right(FromPath, 1) <> "\" Then
FromPath = FromPath & "\"
End If
FNames = Dir(FromPath & FileExt)
If Len(FNames) = 0 Then
MsgBox "No files in " & FromPath
Exit Sub
End If
Set FSO = CreateObject("scripting.filesystemobject")
On Error Resume Next
FSO.CopyFile Source:=FromPath & FileExt, Destination:=ToPath
On Error GoTo 0
End Sub
