Some may ask, why not just use the GUI to do your magic with SH4 Corruption Management System? Operations take a long time and maybe old Rockin Robbins should get with the modern age and just use the GUI.
Well,
here's your answer. Windows explorer, which you have to call to do file operations, is 10 times slower than the command line when working with large, complicated directory trees like.....Silent Hunter 4 uses! So these operations, which can take 10 minutes, would take an hour and 40 minutes with Windows GUI! That's just not acceptable.
And that's why SH4CMS uses batch files. They're hands down the best tool for the job.
