Unfortunately Delphi reported a lot of memory leaks. Searching on SO I found the following question explaining why this doesn't work: Why aren't descendants of TInterfacedObject garbage collected? There is a workaround

There is a workaround presented there but it requires me (at least if i get it right) to write a custom interface IFileInfo and
