r"""
Find the full path to specified files.
Reports the full paths to the files given through *fname*. We look for
the file in (1) the current directory, (2) in $GMT_USERDIR (if defined),
(3) in $GMT_DATADIR (if defined), or (4) in $GMT_CACHEDIR (if defined).
*fname* can also be a downloadable file (either a full URL, a
`@file` special file for downloading from the GMT Site Cache, or
`@earth_relief_*` topography grids). In these cases, use option *download*
to set the desired behavior. If *download* is not used (or False), the file
will not be found.

Parameters
----------
fname : str or list
One or more file names of any data type (grids, tables, etc.).
download : bool or str
[**a**\|\ **c**\|\ **l**\|\ **u**].
If the fname argument is a downloadable file (either a complete URL, an
@file for downloading from the GMT data server, or @earth_relief_xxy)
we will try to download the file if it is not found in your local data
or cache dirs. By default [``download=True`` or ``download="l"``] we
download to the current directory. Use **a** to place files in the
appropriate folder under the user directory (this is where GMT normally
places downloaded files), **c** to place it in the user cache
directory, or **u** for the user data directory instead (i.e., ignoring
any subdirectory structure).
{V}
Returns
-------
path : str or list
The path(s) to the file(s), depending on the options used.
Raises
------
FileNotFoundError
If the file is not found.
