The file may not delete for a variety of reasons. Remove the try/catch block and see what exception is displayed by your web server.

Also, if an exception is caught, the next file in your array will be skipped because you have i++ in the catch block - you don't need that there because i will just get incremented again when execution returns to the top of the for loop.
