For /? has a pretty good example.

Without extensions FOR is not able to use the /F, /D, /R or any
switches for that matter. It can only do simple sets and/or wildcards
which regular DOS and the Win9x command.com can do, such as:

for %%a in (red blue green) echo The color %%a
for %%a in (*.txt win?.ini) do print %%a

With command extensions, the FOR command can count, (with the /L
switch), read from a file, etc. (with /F) and recurse subdirectories(
with /R), etc.
