>>Hi. I am doing an Array of a folder's contents. How do I test for an empty directory?
>Thanks, Randy

>If you use adir(), check the return value. It will return the number of files found. From help: "If the array exists and ADIR( ) returns 0 because no matching files are found, the array remains unchanged. If the array doesn't exist and ADIR( ) returns 0, the array isn't created."

ADIR() also returns the names of the subdirectories -- so there may not be any files but can have a return >0 due to subdirectories.
