If there is a specific file that is always existent in the directory when it is used (such as TOC.TXT), have the test check for that vice *.* Or if you generate PDF or DOC or TXT files invariably to the directory every time it is in use, key on the extension (*.PDF) for the initial test.
Testing for *.* is like testing for nul: in a directory, it only verifies that the directory exists.
You might also use an if loop and ERRORLEVEL to report on attempts to copy and move, and skip reporting and FTPing if there are no files that way.
