[SAI KUMAR S]

Hi,

     In DSpace 6.3, when I try to export metadata in a particular collection where .csv file will be downloaded in that file how could I add a custom field or column of fulltextpdf column or Name of the file column where can I modify to get this column.

I have attached the .csv file, So please guide me to solution to add a custom column in the metadata.

When I export the metadata so that I could get all the fields including added column. 

Thanks & Regards
