I'm not sure what you mean.
You wrote:
copy ${mountpoint}/MakeMKV.app ${mountpoint}/MakeMKV.url ${worksrcpath}/
This works fine and copies the directory MakeMKV.app and the file MakeMKV.url
into the directory ${worksrcpath}.
But since you don't need MakeMKV.url it also works fine to just write:
copy ${mountpoint}/MakeMKV.app ${worksrcpath}
The copy procedure does not behave differently depending on how many source
items there are, and it does not be have differently depending on whether or
not you put a slash at the end of directory entries. It does not behave
differently in destroot than it does in other cases, and the only thing I could
find in the Tcl documentation about copying across filesystems is that symlinks
are only preserved when copying within a single filesystem, which isn't
applicable here since you're not copying symlinks.
