The 'filesize' section is from [1], only the word 'bytes' has changed to 'B' and 'filesize' in two places. It looks like there are other copies of this same snippet in a Google search, but this one shows direct descent from [2] via the 'forked from' tag, so is probably the root of the trail. Not saying that's where you got it from, but this is clearly a derivative work.
Then your 'showFocus' section is from [3] and [4], both posted under the same username. I can't immediately see any other path this piece has developed from and it doesn't seem as significant, but your copy only differs by some trailing spaces.
I stopped looking after realizing over 50% of the first file I looked at was stolen from other sources without attribution.
