Windows 7: is there an app that will compare 2 drives and duplicate differences

Well, i think I'm done. (fingers crossed) I took your advice on those apps you listed and looked thru a few of them. Karen's replicator looked like the kind of app i like....free and good. The kind of app you don't see a lot lately, those which are written by people who aren't looking to cash in but just enjoy writing programs and offering them free. I always seem to find those are often the ones that work well and are very user friendly and simple, and this one was. So i gave it a shot and so far it seems to work great. Thanks for your time and trouble in replying and helping me out.

I use robocopy for this task. Modify the switches to copy anything absent on the destination drive.
(Remove the space between "COPY: DAT" - this text editor insists on planting a happyface there when I remove it)

@ECHO OFF
SETLOCAL

SET _source=k:\pictures\

SET _dest=M:\Pictures\

SET _what=/COPY: DAT /B /MIR
:: /COPYALL :: COPY ALL file info
:: /B :: copy files in Backup mode.
:: /SEC :: copy files with SECurity
:: /MIR :: MIRror a directory tree

SET _options=/R:0 /W:0 /LOG+:PicturesLog.txt /NFL /NDL /XD robocopy
:: /R:n :: number of Retries
:: /W:n :: Wait time between retries
:: /LOG :: Output log file
:: /NFL :: No file logging
:: /NDL :: No dir logging

ROBOCOPY %_source% %_dest% %_what% %_options%


The first time you use this batch file, it will copy everything over, including folder structure. Each consecutive time you use it, it will only copy new files over to the destination drive.

Thats exactly what karen's replicator does. 1st time it copied the whole drive over. Now it just copies files that aren't on the destination drive. It's 2 clicks instead of one, but whats .001 second every few weeks. So i'm good with this.
