File adapters

When you select a file adapter, you supply the name of a specific file or a file name that contains a wildcard. If a source adapter is a file, you can specify that the file be a source trigger. If you use an input file with a wildcard in its name, the Launcher initiates a watch for any file that matches that name. If more than one source for the same watch has a wildcard, the first one to change state is used as the value for the other input sources and output sources that have that wildcard in its name.

Use watch directories only for trigger files to avoid the overhead caused by polling non-trigger files and to ensure the best performance of the Launcher file adapter listener. For example, if the watch directory is FULLPATH/WatchDir and the watch wildcard is set to trigger from *.txt files, do not keep configuration files (*.conf) in the watch directory.
