save already attached pdf

ftr

Can I save again a pdf that is already attached to a bib ? I want to add remarks, underlining etc. to a file that has already been attached to a Zotero note. When I want to save the pdf the file location of the pdf is given for instance as zotero://attachment/24/ Where is that on my pc ?
Is saving possible in this case ?

TIA
