I need to write a DOS batch file which conceptually does this:

SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
SET TARGET=c:\Temp\directory name with spaces\
FOR %%C IN (A B C D ) DO (
   copy "Setups\%%C\Release\%%C%Setup.msi"  "%%TARGET%\%%C"
   echo Similar commands ...
)

Where, for instance,

Setups\A\Release\ASetup.msi would be copied to c:\temp\directory name with spaces\A\ASetup.msi

The problem I’m having is that the command processor parses this very counter-intuitively and doesn’t produce the expected (or even a useful) result.
Is this possible in a single command file?

(I can do it with an auxilliary batch file – but that seems inelegant)

    call copy "Setups\%%C\Release\%%CSetup.msi" "%TARGET%\%%CSetup.msi"

    1. You had a stray percentage sign in %%C%Setup.msi

    2. Then a double percentage in %%TARGET% – you only need one.

    3. You were missing Setup.msi from the end of the destination filename.

    Note: I used call as well, by habit, even though you don’t strictly need it in this example.
