Starting with Crystal Delivery version 10.3.2, Dynamic Text within exported files is now supported.
Without Dynamic Text, files will continuously be overwritten.
For example, on the Export Directory tab, if I select the folder to export a file and name the export file Top Products.pdf, each time the export occurs, the file is overwritten.
If you need to keep individual files for each export, Dynamic Text can be used to accomplish this. Simply appending one of the support dynamic text to the filename will append the date/time information to each exported file, making it unique, and thus not overwritten.
Now when the file export occurs, your file will have unique date/time information added to the filename.
