# Stop Action and Filter Files

This function immediately terminates action processing and will filter the list of open files according to the specified function, mode and filter.

Track variables are typically immediately cleared when an action terminates. This statement retains the contents of the Variable fields until the filter operation is done. If you design a filter which accesses Variable fields, this statement can choose at runtime which files are to be processed when filtered.
