Do you want to move the distribution database or the Snapshot folder?
To move the distribution database see the following KB article,
http://support.microsoft.com/default.aspx?scid=kb;en-us;224071
To send the snapshots to a different folder you'll need to alter the properties on the Publishers tab of the COnfigure Replication dialog.
Hope this helps
