В спецификации утилиты robocopy сказано:

/MOV Moves files (that is, deletes source files after copying). /MOVE Moves files and directories (that is, deletes source files and directories after copying).

In some situations, you may want to move files instead of copying them, especially if disk space is at a premium on your network. You can use the /MOVE switch to delete source files from the source directory tree after they have been successfully copied to the destination. /MOVE also deletes empty directories from the source directory tree. Even with /MOVE specified, however, Robocopy deletes only those source files that it successfully copies to the destination. There is no guarantee that a skipped source file is identical to its corresponding destination file (even if the file times and sizes are identical) until immediately following a successful copy. For that reason, some files and directories (such as skipped Same files) might remain in the source tree even when /MOVE is specified. You must determine whether to delete the remaining entries, and do so manually.

Т.е. это утилита именно копирования, а удаление происходит уже после успешного копирования и никак иначе.
