i put an upload file button on my website.

i changed the upload file limit to 500000000

the file i want to upload is 50mb

when i uploaded it, it wasn't in my uploads folder.

i uploaded a smaller file and it was there. i changed the script to accomodate for the larger file size but the file never added.

why?

how can i fix this?

also when people upload a file to the site, it sends me an automatic email. however, the person who is sending the email comes up as 'unknown'. how do i change that so i know who is sending me the files?

a quick reply is urgent
