public File getFile(VirtualFile mountPoint, VirtualFile target) throws IOException
File
for the given path within this filesystem. Some filesystem types will need to make a copy
in order to return this file; such copies should be cached and retained until the filesystem is closed. Depending
on the file type, the real path of the returned File
may or may not bear a relationship to the virtual
path provided; if such a relationship is required, it must be negotiated at the time the filesystem is mounted.
