Check File Names
The output of the Check File Names process includes the Check File Names 2 window, revealing the results of the filename check. If all of the specified files were found, the following message appears.
If one or more specified files were not found, an error message appears. The missing files are highlighted in the data table and printed to the log.
Finally, if none of the specified files were found, it is likely that the wrong folder was selected.
