Blue Iris Clips and Files - Disk Usage Utility

Changing two lines as follows:
913 - :
if ($cur_ary_cnt -gt 0 -and $Days -ne 0) {

2722:
if ($timestamp_output_csv_files_flg -and $archive_lifetime_days -ne 0) {

allows the option $archive_lifetime_days to be set to negative numbers. ANY negative number will prune ALL the CSV files. Other values behave the same as before.

I don't need history of usage, this cleans up the CSV files created for the report.
Nice. I'll make the change.
 
Script updated to V7.1. See post #1 to download the file.
