I don't think that this is all that helpful. It's an entirely too vauge grouping and will just get lost.

"Seperate_Digital_Categories", what in the world does that mean?

Exterminate"? I don't think that that word has any usefulness in the context of programming. The concept of deleting or removing something based on "before or after a certain date" is known as pruning IIRC. Also, the default values that you've assigned to this function make it do absolutely nothing which doesn't make any sense. If a default value doesn't actually do anything then it shouldn't exist.

I don't think that low-level stocks should be writing anything to any files, calling process should be the one to do that.
