references a set of Local File or Remote File objects that were retrieved or processed by a task. The File List element defines the variable name for the File List, and uses the File Set element to define the target directory where the files are located. A File List can have one or more File Sets, which allows you to create a single File List that contains files from multiple directories.
The File Set element also allows you to add optional file filters that let you search for files with specific attributes. The files to select can be included and excluded based on various filter criteria:
Wildcards (for example, *.* or *.txt or pay??.xls)
Regular expressions
Date/time ranges
Size ranges
For instance, you could add a File Set to a Zip task that compresses any files that end with an .xls extension which were created after 2010-12-15 with a size of 100 kb or greater.
You can iterate through each file in a File List variable using a Loop.
