I would like a Windows batch file for DOS (not Powershell)  to move JUST 100 files from folder S:\SOURCE to folder D:\Destination INCLUDING files WITHIN SUBDIRECTORIES (duplicate filenames not moved).  

I want the maximum number of files moved to be 100.

Give this a try:

@echo off
setlocal EnableDelayedExpansion

set BaseDir=S:\Source
set DestDir=D:\Destination
set MaxFiles=100

set Count=0
for /f "tokens=*" %%A in ('dir /a-d /b /s "%BaseDir%\*.*") do (
  if not exist "%DestDir%\%%~nxA" (
    set /a Count+=1
    if !Count! GTR %MaxFiles% goto :Done
    move "%%~A" "%DestDir%"
  )
)

:Done

Bill,

It doesn't matter which hundred are moved.

Also, it seems that there is a syntax error in your code.

Thank you.

Sorry, looks like I forgot a trailing single quote on the FOR line.  Try this:

@echo off
setlocal EnableDelayedExpansion

set BaseDir=S:\Source
set DestDir=D:\Destination
set MaxFiles=100

set Count=0
for /f "tokens=*" %%A in ('dir /a-d /b /s "%BaseDir%\*.*"') do (
  if not exist "%DestDir%\%%~nxA" (
    set /a Count+=1
    if !Count! GTR %MaxFiles% goto :Done
    move "%%~A" "%DestDir%"
  )
)

:Done

Bill,

The code just hangs. No files are moved. Is there another error in it?

Thanks.

I tested it here and it did work fine.  How many files are under the base folder, it can take a while to locate all the files before it starts moving the first 100.
