How to compare two directories?

I've copied a large directory tree from my machine to an external disk.
I'd like to verify that everything copied accurately. How can I do that?

The "fc" command works well, but it doesn't have a switch that will do
subdirectories.

I'm thinking that some combination of the "for" command and fc will do
it, but the syntax of for is escaping me.

Here you go:

@echo off
SetLocal EnableDelayedExpansion
set SourceDir=d:\logs
set TargetDir=e:\Test

for /F "delims=" %%a in ('dir /s /b "%SourceDir%"') do (
set Name=%%a
for %%b in ("!Name!") do (
echo fc "%%~db%%~pb%%~nb%%~xb" "%TargetDir%%%~pb%%~nb%%~xb"
)
)

Remove the word "echo" in the third line from the bottom to activate the
batch file.

Thank you. This is excellent. And posted in only 20 min!

Output is a bit verbose, so I have to pipe it to a file.

Open 2 instances of Explorer and put them side by side.
