This portion of the code looks inside a folder (you can include subfolders too) and changes a specified file extension to another one. This
VBcoders
Dim fileEntries As String() = Directory.GetFiles(tbBrowse.Text)
' Process the list of files found in the directory.
Dim fileName, ConvTo, ConvFrom As String
ConvTo = tbExt.Text
ConvFrom = "." & tbCurExt.Text
For Each fileName In fileEntries
Dim ff As String = Path.GetExtension(System.Convert.ToString(fileName))
Dim File1 As String = Path.GetFullPath(System.Convert.ToString(fileName))
Dim File2 As String
If ff = ConvFrom Then
File2 = Path.ChangeExtension(File1, ConvTo)
File.Copy(File1, File2)
File.Delete(File1)
End If
Next fileName
' if you want VB to also search the subdirectories...
