the system can't find the specifeid path

quote from log:

13-11-2006 18:03:38 - ERROR: #3 - Het systeem kan het opgegeven pad niet vinden. [CopyFile1] (\\Cs-dc-01\Data\I SilverBack\Support\Trainingmateriaal\Training\Courseware\SilverBack Operations\SilverBack Operations 2.2.1\Technical WorkFlow and Training Program 5.0 v3\Documentation_Library\RUNBOOK Policy Modules\RunBook Policy Modules\Citrix MetaFrame.doc ----> C:\Documents and Settings\p.vandermeij\Mijn documenten\_Server Bestanden\I SilverBack\Support\Trainingmateriaal\Training\Courseware\SilverBack Operations\SilverBack Operations 2.2.1\Technical WorkFlow and Training Program 5.0 v3\Documentation_Library\RUNBOOK Policy Modules\RunBook Policy Modules\)

but when i copy the path, and past it into my explorer adres bar,it comes up just fine.

what is the problem?

The maximum path length under Windows of 255 characters has been exceeded. Check your destination path:
