Android Question Getting the size of a directory

[Devv]

How could i get the size of a directory (/sdcard/whatsapp) for example?

Get all files from the folder recursively
Iterate through this list and get the file sizes
The sum of all filesizes is the size of the folder

Sub CalcSize(Folder As String) As Long
   Dim size As Long
   For Each f As String In File.ListFiles(Folder)
     If File.IsDirectory(Folder, f) Then
       size = size + CalcSize(File.Combine(Folder, f))
     End If
     size = size + File.Size(Folder, f)
   Next
   Return size
End Sub

I´ve put this (slightly changed) into the code-snippets.
