'Usage Dim instance As MemoryFile
public class MemoryFile : AbstractFile
As long as you hold at least one instance on a MemoryFile or a MemoryFolder located in a specific root name, all files and folders in that same virtual ram drive stay alive. When a root name is no longer referenced, all its content will get garbage collected later.
To make sure the memory allocated for a MemoryFile's data is released, as soon as you don't need the file anymore, call FileSystemItem.Delete on that MemoryFile.
