My testing of KiXtart v4.21-RC2 seems to work as expected with the COPY/MOVE/DEL functions.

The only thing I found maybe odd was that having code to COPY C:\TEST1\ C:\NEWTEST\

Depending on how you expect things to happen. In DOS saying to copy C:\TEST1\ C:\NEWTEST\ would attempt to copy all the files in C:\TEST1\ to C:\NEWTEST\ but since the folder does not exist, would do nothing. KiXtart doesn't copy the files either, BUT it DOES create the folder C:\NEWTEST\ which I would not expect.

Other then that, all other situations of COPY/MOVE/DEL worked as I would expect.
