Thumbs down [Q] why is "simple explorer" file manager unable to delete my files?

using slimkat 4.2.2, on galaxy (bell i747m). when i try to delete a file or folder via the default file manager "simple explorer", i find that the file deletes perfectly and does not show up on phone... but when i plug my phone in, windows is able to see that file and i am able to access it. what seems to be the problem. so far i am enjoying slimkat, but this is a little disconcerting.
