A typical scenario for the File Binding Component as a service consumer is polling a directory for files that match specified file names or file name patterns. When polling a directory, you can specify the following:
Polling Interval - Use the pollingInterval message property to specify how frequently to check the directory.
Pattern Matching - If the fileNameIsPattern message property is set, then the fileName message property indicates the file name pattern for files to retrieve. Patterns that can be embedded in a file name include an incremental counter, a UUID identifier, or a timestamp.
Refer to the section File Name Patterns for more information.
