Importing to table with upload file

I can import xls file to the table, but the table has 2 upload fields for pdf’s.
Is it possible to import to the table already with the files? I’ve tried to upload the files to the server and then add the url on the field but, although it imports the url value, if I open the link url it shows a blank page and there is no pdf preview.

Is there a workaround or it’s just not possible? (The files are uploaded to a folder when we do it on the webiste)

Thanks in advance

You may use Row_Import server event (see the topic Server Events and Client Scripts in the help file) to set the field value of the upload field. If the upload field is BLOB type, you need to copy the existing file data to the field. If the upload field is string type, you need to copy the existing file names.
