What I need is the ability to define a search pattern for files that meet specific criteria (wildcards, date created range, last modified etc.), will search thru subdirectories and copy the directory structure along with the marked files but no others.

Like this; Say I want to copy only those files modified after a specific date within a directory tree. The resultant copy should mimic the original directory tree but contain only those files marked for the copy. In other words, every file copied will end up in a directory that itself may be in another, empty parent directory (unless the file was at the root of a drive).

Anyone ever used/heard of a utility that does this? I haven't had any luck in the usual spots (winfiles, tucows etc.)
