Merge two folders with a lot of sub folders and files
I have a situation where there are two folders that need to be merged to one. The folders are about 8gig in size and contain many levels of sub folders with documents and some images. The documents are going to be mostly xls, xlsx, doc, docx, ppt, txt, pdf, jpg.
Many of the files are duplicates although one folder may have a more recent document.
Folder A
-- SubFolder A.1
---- SubFolder A.1.1
------ Document A.1.1 somefile.docx last mod 6/12/2015 3:45pm
-- SubFolder A.2
---- SubFolder A.2.1
------ Document A.2.1 somefile.docx last mod 2/21/2015 10:21am
Folder B
-- SubFolder B.1
---- SubFolder B.1.1
------ Document A.1.1 somefile.docx last mod 1/1/2015 1:20pm-- SubFolder A.2
-- SubFolder B.2
---- SubFolder B.2.1
------ Document B.2.1 somefile.docx last mod 6/5/2015 12:53pm
This is on Windows Server 2008
My goal is to Merge everything in Folder B to Folder A where only folders and files get added to A from B that are not in A and only files from B get copied to A if they are newer than in A
Am I better off writing a vbscript or using something like RichCopy?

The built-in robocopy should be able to do that.
/xo: eXclude Older files (don't copy older files over newer files)
/r:0 no Retry (usually not necessary in a LAN)
/np: No Progress (control characters make the log file hard to read)
/tee: output to console and log
/L: test mode; only Log what would be copied; remove this to run the copy for real.
robocopy.exe "F:\older\B" "F:\older\A" *.* /s /xo /r:0 /np /tee /log:"C:\Temp\robocopy.log" /L

XCOPY is more than good enough too and can be less likely to cause issues as it can't possibly do any deleting due to incorrect settings for instance.
xcopy /d /s /-y /c /z x:\FolderB\*.* y:\FolderA
The /d copies if newer or does not exist
Adding /L will test but not copy any files.
If you also want hidden, system files or to overwrite read-only etc. can use the other options available on xcopy but above would do most.
