I am thinking of going through Portable XAMPP Lite and deleting all the images. I'm pretty sure that would reduce the file size a great deal. The trouble is, if I did that, I'm not sure certain parts of it (like phpMyAdmin possibly) will still work, or whether I will still be able to actually navigate those parts that use the images if I need to later.
The reason for wanting it even smaller is because I have a really small flash drive and it barely fits on there - and I would like to be able to put more stuff on there. (I am planning to buy a bigger one soon, but still, I'd like to have this hypothetical Super Small / No Fluff version on there as well)
