A page cannot be found error (404) means that that are most likely trying to access the wrong URL or path.

Go back and check on that. We don't know for sure because we would need to see your relevant code.

My Code

Your code is working. All i did was copy your code and paste it to a new page on my test IIS server, not visual studio dev server.

All i had to do is update this line of code:
hpf.SaveAs("D:\\D drive backup\\Destination_Folder\\" + filename);

and of course remove the code you have in your page load subroutine.

It worked without any issues was so-ever. no 404 errors, i uploaded multiple jpg files.

Where/when/what are you doing when you see the page cannot be found error?

Member Avatar for amrita111

for nearly around 30 fiels it is working.....bt it is not working for 500 jpg files....try it for upload of 500 jpg files

Member Avatar for JorgeM

If its working for at least 2, then we know that the basic functionality of the multiple upload works.

Where and when do you get a page not found error?
