Does `client.Host().File()` load the enclosing directory into memory? | Dagger | Page 1

I am doing a client.Host().File() to copy a single file into the container workspace with withMountedFile. However, I am seeing that the enclosing directory is also "transferred" into memory? In this case it's not desirable as that directory is very big. Is it better to do client.Host().Directory(includeSingleFile).File("myfile")? Seems counter-intuitive.
