pdfs attached folder
As far as I can see, now each pdf attached are saved in a separate folder (with a name that gives me no useful information about its content). If you want to copy that pdfs anywhere else, you should do it file by file. Why do not have one folder, where all pdfs attached are stored (as in EndNote)?
1. There is no guarantee that PDF filenames are unique
2. PDFs are not the only attachments; web snapshots consist of multiple files and for these separate folders are needed
(and if you search around the forums and the documentation you'll find other reasons
But if you'd like to organise the PDFs yourself you can try linking, instead of importing attachments; and you can use a plugin like ZotFile.
I have looked in the forum and tried to follow the people's suggestion, but the search result always turn out no document at all. it is my first time to use smart folder on mac. so i am very grateful for help.
