Copy file from network

Hello - Any help on copying the file from network location to temp folder. I am trying something like this but getting this error. I can access the file from the same machine where I have EPF and all paths are good.

Copy file src_path to tgt_path

STFileSystemException: Failed to copy file or folder //myserver/myfile.pdf (Error: (null))

Ignore this. Seems working only by mapping like a drive.
