Access to remote folder

Hi,

I have an app which must read, change and save (update) files on remote PC.

I have a special user/password to access the remote computer.

Is there any way to loging to remote computer from inside the app, do the job and then log off.

App works fine if I logging to remote PC before starting nut I don't like this. I'd like to have evrething hidden from enduser.

Thanks

Oleg
