I had the same issue before and nothing would work. The only way I was able to remove the file was to actually delete the folder it was in, which took care of the file as well. However, mine was a music folder, so yours is an essential folder. I dont know how to do it, but possibly Broni does. Is there a way to move whatever else is in the folder to another folder and then delete the first folder with the vulgar files in it? (lol I know, wordy).
