You can try using a symlink.
- Have the other person upload to specific directory directory or filename.
- He needs to tell you what the specific path is.
- Login to shell as your user and change to a directory you want the link in.
- Run the command 'ln -s target link' where target is the path and link is the name of the link.
For example, if he tells you he uploads multiple files to the directory /home/bob/client, and you want to access them from /home/alice/bob, the command would be
'ln -s /home/bob/client /home/alice/bob'
