Why MOSS2007 Content Import Fails?
And another discovery about SharePoint 2007 content deployment. You should be aware of forbidden file types. When making mass import of content then import fails when it finds forbidden file type. All files after first forbidden file will not be imported. I don't know if this blog entry has some value or not but maybe I will save somebody's time about hours or days :)
