Leanne,
Thanks for your reply.
I may give more infos. about this issue.
I have added 300 pdfs in a special folder last week in Endnote, today I have attachted 3 new pdfs in this folder.
How can I only add this three new pdfs into Endnote in a great easy way, Every day I may read some new articles which are related to a special topics.
Of course, I can delete this folder in Endnote, and import alle files in this folder again . but I find this is really not efficient.
Kind regards,
Yaakov
