Dear Galaxy Team, 

As a part of in-house automated cleaning of data set from our production galaxy service, 
I am finding difficulty to get the galaxy assigned file name (galaxy-root/database/001/dataset_001.dat) 
for each data set from the corresponding database. We are using PostgreSQL and
when I queried through the table name called 'dataset', couldn't figure out the values for
external_filename or _extra_files_path. 

For example:
>> select * from dataset order by id DESC limit 10;  
  id   |        create_time         |        update_time         |   state   | deleted | purged | purgable | external_filename | _extra_files_path | file_size 

 70805 | 2011-04-22 20:49:55.319709 | 2011-04-22 20:50:26.643807 | ok        | f       | f      | t        |                   |                   |    421593

Could you please let me know where I can locate the file name from other tables or 
do I need to set up any configuration. 

Thanks in advance,
