Rars are useful when you're posting huge files like DVDs which would

Easier handling in that one uploads fewer parts. At least some
providers have file number upload limit. It depends on the number of
files. I've uploaded photo series before (only c. 100-200 per set, not
5,100!) and it makes life much simpler.
