Breaking up a huge database backup file. I actually worked during three different shifts. I would copy from one huge file into smaller files that were broken up based on the starting letter of the database table names. The three sessions were: 5-6:30 pm, 7:30-8:30pm, and 10:15-12:00 am (midnight). Mindless work, but it just took forever to copy and paste that much data. As a mater of fact, none of my text editors would open that big of a file. I only got one editor to open the whole big thing.
