We need it. Not as much for virus or spam as such, but because some are looking for files of a certain size-range.

Me, I like to look for movies that last longer than 15 seconds to two minutes. That means, generally, I have to check 450 of 500 results off the list before I get to the ones I want. With this filter, I could just look at 50 results and get to what I wanted faster.

And how do you actually train the junk filter to sort out specific sizes? I took all files smaller than 10 MB and marked them junk. Then, I hit the movie of Iron Maiden's Number of the Beast about 100 times marking it as Not Junk. The files I had marked had nothing linking it to this file, yet I couldn't learn the filter that the movie wasn't junk.

So, How do you do that? (I know this isn't the place to ask it, nor do I expect answers here. I am just proving a point here, seeing as people say the junk filter works. It doesn't for me, and I really can't figure it out)

Edit: The Iron Maiden movie was about 53MB
