If you need a solution like this that works great and is very inexpensive.....duh it's free (at least at this time).....then check this out.
Colligo Reader enables you to easily download content from SharePoint sites to your laptop - so you can access the content offline, rather than having to copy files one by one through a browser. Colligo Reader is completely free for individual users and very simple to use. Reader is a client-only application - no server modifications are required. The install package is just 4.6MB in size, so it takes less than a minute to install (no license keys are required). Colligo Reader works will all shipping versions of SharePoint, including Windows® SharePoint® Services (WSS 3.0 & 2.0), Microsoft® Office SharePoint® Server (MOSS 2007), and SharePoint® Portal Server (SPS 2003).
