Description¶

This function returns the default reports cache folder location. The default folder is a folder named Cache in the Reports folder (e.g., c:\examples\weborder\reports\cache). The function utilizes the ReportsFolder function and is used by the [ReportCacheFileName](report-cache-file-name.md

An empty string is returned if there is no such folder or if there is no cApplication object.
