Hi,
Just an idea, when we wants to make changes in the document attached in Workfront. Then first we have to download the file, make changes and upload.
Workfront can provide facility to open the document, make changes and save it. So, once opening the document, it will create a temporary file on PC, then make changes and click the save button. This can be possible to connect the document at the same link in Workfront and will replace the old one. So then we dont need to download specially in PC and making changes and then upload.
Regards
Kundan
