I tested it with this:
Code:
cmd /k ""C:\trashme\scripting\amxxpc.exe" -o"C:\trashme\other\$(NAME_PART).amxx" "$(FULL_CURRENT_PATH)" && copy "C:\trashme\other\$(NAME_PART).amxx" "C:\trashme\plugins\$(NAME_PART).amxx""
and this:
Code:
cmd /k ""C:\trashme\scripting\amxxpc.exe" -o"C:\trashme\other\$(NAME_PART).amxx" "$(FULL_CURRENT_PATH)" && copy "C:\trashme\other\$(NAME_PART).amxx" "Y:\test\$(NAME_PART).amxx""
And both work flawlessly.
The only thing that I changed (other than the file paths) was I put spaces around the &&
