Hi frnds

In app i want to give a link when it clicked all the files from the specific folder must be copied to client machine.
what i was trying is using
File.Copy(Source,Destination,true)

this statement is working fine if i m using the server as the client but if i installed this app on the server and access this app from the client machine it does not copy any file.

pls tell me the safest way to copy a file from server to client machine.
