# a relative filepath, or simply a filename.  
# Relative filepaths are always relative to the home directory
# of the SFTP/SSH user account.  There is no such thing
# as "current remote directory" in the SFTP protocol. 
# A filename with no path implies that the file is located
# in the SFTP user account's home directory.
