<td class=""><p>I have numerous hdf files dowloaded from ftp site and saved it to my 
local directory.The hdf files has level 1 and level 2(e.g. 
A2001037040000.L1A_LAC.hdffiles.hdf, 
A2001037040000.L2_LAC.hdffiles.hdf). How will I project the level 2 
files ONLY in batch process and automatically create a directory for the
 projected files?And what should I do so that I would be able to 
project/process the newest files I have downloaded EVERYDAY, this means 
that the projection should update everyday and if there are files added 
that should only be projected?</p>

<p>IMPORTANT: The hdf files for today aren't available yet so the newest
 files to be projected/processed are those files uploaded yesterday 
because all the files uploaded in the ftp site are delayed one day.</p>

<p>Thanks in advance for your help! </p>
