The file name is always sent, and is useful both to help the user 'recognise' the content and possibly to interrogate the file extension to help determine the file type. However I know from experience that Internet Explorer definitely used to in older versions send the entire path.
It's difficult to find an authoritative confirmation except this apache fileupload control doco. When you upload a file, it is effectively being transferred from the client's computer to the server hosting your application. If you're developing the application, most times, both client and server are the same machine your computer. Once the application is deployed however, there could be any number of clients connecting to the server, each uploading a different file.
Knowing the full path of the file on the client's computer usually isn't necessary - you'll often want to do something with the file contents. Your examples seem like ASP. You can get at the uploaded file's contents by reading the raw stream FileUpload. InputStream or by saving the file first FileUpload. SaveAs , then accessing the saved file. It's your responsibility to save the file, if you want it to be accessible after the current request - if you don't, ASP.
NET deletes it. If you don't, the client's browser won't send the file, and you'll spend quite a few minutes wondering what went wrong. Edit: This answer describes how to get the path to a file on the server. It does not describe how to get the path to a file on the client, which is what the question asked. The answer to that question is "you can't", because modern browser will not tell you the path on the client, for security reasons. Firefox and other modern browsers consider this to be a security flaw and do not.
However, this appears to be have been fixed in IE 8. Perhaps you should instead evaluate why you need the full path to the file as it was located on the client's system.
I think it is really superfluous information that should never be posted at all. All you should be concerned with the is the file name so that you can save the file without making changes to the name. At this moment I also DO get the full user's local path. It's only from 1 machine that I can replicate this issue, but it really does give the full path of the file at the machine of the user.
This is a end-user of our application which is hosted on a off-site server. So it's not on the local machine nor on a local server from which it might happen to be a share. I had sort of the opposite issue as the original poster: I was getting the full path when I only wanted the filename.
Any computer joined to domain will give you back the full path for the filename. I tried this on several different computers with consistent results. I don't have an explanation for why, but at least in my testing it was consistent.
This dumps the file in your temp folder with file name, then after that you can call it and not worry about it. Because it will get deleted if it is in your temp folder for an amount of days.
I'm using IE 8 on two separate machines. Each still uploads the full local file path. GetFileName fileUploadControl. FileName appears to be the only way to ensure that you only get the filename.
Check this post under FileUpload Control. This change prevents leakage of potentially sensitive local file-system information to the Internet. By the way, I am using Visual Studio I don't know if there is a difference with the other version. This will not problem if we use IE browser. This is for other browsers, save file on another location and use that path. You can't get full path of a file at client's machine.
Your code might work at localhost because your client and the server is the same machine and the file is at the root directory.
But if you run it on a remote machine you will get an exception. On Internet Explorer Options, on security tab click on custom security button, there have an option to send the local path when loading some file to server.

GetFullPath FileUpload1.
Applications should be aware that consecutive calls to the GetFullPathName function with a relative path may produce different results if the current directory changes between the two calls.
To avoid problems caused by inconsistent results, multithreaded applications and shared library code should avoid using relative paths. If a relative path is received, it should be consumed exactly once, either by passing the relative path directly to a function like CreateFile , or by converting it to an absolute path and using the absolute path from that point forward. For another example using dynamic allocation, see GetShortPathName.
