All ZTF products file names, including all types of images and associated tables should have the following  structure\footnote{easier for regular expressions} (see exceptions below):\\  \_\_\_\_\_\_\_.\\ \_\_\_\_\_\_\_.\\  The various constructs are:  \begin{itemize}  \item{{\bf project} - project name {\it ZTF}.}  \item{{\bf instrument} - instrument name, either {\it S} for science camera or {\it F} for focus camera.}  \item{{\bf unique_date} unique\_date}  - unique UTC date in format YYYYMMDDpFFFFF (e.g., 20160101p78911), where F is a fraction of day digit. For coadded images, this will indicate the mid date. For catalogs, etc, this will be empty string. For subtraction images this will be the date of the new image (not reference).}  \item{{\bf CCDID} - CCD ID. 0 to 16 for science camera and 0 to 3 for focus camera. For data which is a product of several different CCDs this will by "M" (for multiple).}  \item{{\bf AmpID} - Amplifier ID, 0 to 3. If amplifier is not defined than use empty string. If data is based on multiple amplifiers

\item{{\bf filter} - String containing filter name (e.g., "C" [for clear] "g" or "r" or "i"). If data product is based on multiple filters then use "M".}  \item{{\bf Type} - One of the following image/data types: s (science), df (single dome flat), b (single bias), sf (super flat, based on coaddition), sb (super bias), f (focus image), ds (detected sources), fs (forced sources), sb (subtraction image),  cs (coadded science image).}  \item{{\bf unique\_id} - unique ID specifier for image.}  \item{{\bf FILE\_TYPE} - file type (e.g., 'fits', 'fitstab', 'hdf5').  \end{itemize}  Exceptions: some tables like individual sources light curves.
