HLL - Upload large size pdf file in publication

Solution:-

Step 1 : Upload a small size pdf via application (apanel->manage publication).
Step 2 : Find out the place where it is stored ( director name ).
Step 3 : Identify the name of uploaded file in the storage directory ( because the file is saved with an encrypted name). To get the encrypted file name, we can check the table named 'hll_downloads'. Use the following query to find out the exact item. 

<source lang="sql" highlight="3">SELECT * FROM hll_downloads" WHERE "download_name" LIKE '%Annual Report 2017-18%'</source>

Step 4 : Transfer the large size file to the storage directory and rename it with the encrypted filename, that we already discovered from the database. Also remove the dummy file we have added earlier, from the storage directory.(Done by hosting dept)
Step 5 : Please not that, no need to give the file extension just rename with encrypted file name.
Step 6 : Check the new pdf via application. Method : apanel->manage publication->from the list click on view icon->download pdf.
