FileDeleteWC Script Function

Posted on 74 views

The Wonderware® InTouch™ script function FileDeleteWC() takes a given
directory path, along with a given filename (including wildcard characters
(example: ABC???.*)) and it will delete the specified file(s) under the
specified directory. FileDeleteWC() is a quick and easy way to delete one or
more specified files from within an InTouch application. The given directory
path and files can reside either on the local node or a remote node.

FileDeleteWC() will return value a of one (‘1’) if it is successful or a zero
(‘0’) if it fails. FileDeleteWC() will skip any sub-directories in the given
path—only files will be deleted. If a file has read-only properties or it is
hidden, then FileDeleteWC() will fail.
