You could use a DO WHILE .T. -loop with TRY/CATCH or ON ERROR [errorfunction] around the code that tries to open the file. As long as the file doesn't really exist on the disk VFP will throw a "file does not exist" error which you can catch and not let the program exit the loop until the file is successfully opened. Add error handling for other errors, as well as a case for exiting the loop after, say, 10 seconds, if the file never appears.
