When working on the CSG-globe problem, I found myself deleting vast 
amounts of automatically created data to make room for new stuff.
Some times I deleted files too quickly because Povray hadn't gotten that 
far yet. And sometimes I deleted too little.

So here's a trick so that povray can do it for you

#declare Filename = concat("/data/povray/Mutilated 
Earth/data/flatplane/flatnodes.", str(frame_number,-5,0));
#debug "Loading the mesh object. . .\n"
#include Filename
#debug "Done.\n"



/*
The next trick does not delete the file but reduces its size to 0
when #declare SetForDeletion=true; is found in the file.
*/

#ifdef (SetForDeletion)
   #if (SetForDeletion=true)
     #fopen DataFile Filename write
     #fclose DataFile
   #end
#end

Cheers
