Save a copy of the file to specific folder, from a LinkLabel Hyperlink

Question

I have a program that creates a list of hyperlinks to the files i search for. I can click the resulting hyperlink and the PDF opens. I would like to also have it make a copy of the pdf on my C: also without dialog. The source of the files is from the network. FileSearchButton_Click will search a directory for files with the content that match my search string.

aLinkLabel_LinkClicked is where I feel the copy action should be done
