Subfolder question...

My goal is to move all files/folders created within a specified year to a folder named for that year, while keeping folder structure intact. Kind of like below:
Root Folder
->Folder 1
--->Folder 1A
------>File
Would move as
2009
->Folder 1
--->Folder 1A
------>File
Hope this makes sense
