Free utility or inbuilt program to compare source & destination files

Hi Win7 64 pro
I have copied 2gb using Teracopy to a folder, it showed at least one where path not found.
It has no means of selecting that line and showing me the source file, I cant even copy out the address.

Its ok as along as i get OK in its test, else if I get a red warning it then doesn't offer a means of attempting that source file again. It also doesnt have a way of putting those to the top of the stack. You have to scroll through 2Gb of files to find them.

Then I managed to exit teracopy, now I havent a clue what files needs copying across.

I could do with a second prog to compare source and destination and repair any differences etc.

Any suggestions ?

I had hoped Terracopy would do this.

You can use the built-in RoboCopy and use it only to compare files and folders, NOT to copy anything. Start a command window (cmd.exe) and use this syntax:

robocopy "c:\tools" "c:\toolscopy" /E /L

c:\tools is the source
c:\toolscopy is the destination
/E will include subdirectories incl. empty ones
/L will only do a compare and not copy anything

I changed this in the source folder: one changed file, one new file, one new empty directory
The output from robocopy:

Newer 27 tempEMETfolder.txt
New File 26624 TestBlank.exe
New Dir 0 c:\tools\emptySubFolder\

Another possible solution

What I use - mostly when I want to roll back the system to a system image backup but keep recently added personal files and folders is to copy existing files and folders including directory structure to another partition then use TSR Copy Changed Files to only transfer the files needed back to the current partition.

Example:

First choose Test Copy and inspect the log. No files are actually copied at this stage. If it looks okay - go ahead and copy.
