Partial FileSize Search when Mariner is restarted does not look in sub directerories

[BlueFinBima]

When Mariner restarts and there is a print in progress, this Mariner does not know the filename being printed. It therefore takes the Total Bytes of the print and tries to find a file in /mnt/usb_share/ that matches this size. It does not look in subdirectories and probably should.
