FAQ.How to check if a folder/directory has subfolders?

Answer: You can use code like this to check all items in a folder:
Example 
Function HasSubFolder(folder as FolderItem) As Boolean
  dim c as Integer = folder.Count
  
  for i as Integer = 1 to c
    dim item as FolderItem = folder.TrueItem(i)
    
    if item<>Nil and item.Directory then
      Return true
    end if
  next
  
End Function

We use trueitem() here to avoid resolving alias/link files.
Also we check for nil as we may not have permission to see all items.
And if one is a directory, we return without checking the rest.
