I have a tool that takes a pdb file as input.  The authors of the *compiled* code require that the suffix be either &quot;.pdb&quot; or &quot;.ent&quot;.  When I upload a .pdb file, the filename that gets fed to the tool now ends in .dat.  What is the best way to get the original file extension stored in the file database?  <div>
