I need a small component for checking for filetypes. It gets params of unwanted filetypes and checks, if an uploaded file (uploaded to a server) is present or not. Checking of zip/rar etc. archives must be supported. Also simple checks like checking for the file-ending (example: [url removed, login to view], here the file is not a jpg of course, it is a video, an asf-file) must be supported. This is only a small project, so please be realistic with your bid. I will not pay more than 100$ for it and a good 10-rating. Thanks.
