Does "mappene" also mean "the files." In (American) English, this sentence means that there are actual file folders sitting on top of the computer (rather than data files on the computer's hard drive).
Mappene means file folders (e.g. 'my documents') when you say 'på datamaskin'. Files are 'filer'.
But in English 'folders on the computer' can either mean file folders or physical folders, and it is impossible to tell the difference out of context.
