hi experts
i need to upload large file in my website ( < 200 MB ).
i changed my web config:

C#

<system.web>
     <httpRuntime maxRequestLength="200000" executionTimeout="3600"requestValidationMode="2.0"/>

......
</system.web>

and

C#

<system.webServer>
   <security>
       <requestFiltering>
           <requestLimits maxAllowedContentLength="200000000"/>
        </requestFiltering>
   </security>
</system.webServer>

in local host it is correct but in server i got this error:

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

thanks in advance

It does not look like size issues.
Looks more like path issues, try to post code and the values of the relevant Path variables

I agree with Maimonides, it's related to path issues because of the error message which you got.

First, try to upload a small textfile(5 or 10 kb), if it fails then path is issue. Without seeing your code, I can't tell you more.

If the same code works on local but doesn't work on hosting server, then its not the issue with the code. Just check the configuration; especially the path of the file. May be you are giving the absolute path of the file to be uploaded and that path is not existing. The error you have mentioned refers to the issue of path.

its my code:

C#

if (oHttpPostedFile.ContentLength == 0)
                            {
                                //Your picture file was not successfully uploaded!
                                throw (new            MyWebApplication.ApplicationException(Resources.Messages.ErrorMessage010));
                            }
                            else
                            {
                                var realFileName = Path.GetFileName(strPathName);
                                var userfileid = 0;
                                if (extension != null)
                                {
                                    userfileid = InsertFileInDb(userID, realFileName, address, extension.ToUpper(), oHttpPostedFile.ContentLength / 1024, 0);
                                }
                                var writePathName = HttpContext.Current.Server.MapPath(string.Format("~/UserFiles/{0}/{1}", userID, userfileid + "-" + realFileName));
                                oHttpPostedFile.SaveAs(writePathName);

                                var backupDirectory = HttpContext.Current.Server.MapPath(string.Format("~/UserFiles/{0}/BackUp", userID));
                                if (Directory.Exists(backupDirectory) == false)
                                    Directory.CreateDirectory(backupDirectory);
                                oHttpPostedFile.SaveAs(backupDirectory + "/" + userfileid + "-" + realFileName);

                                return strFileName;

                            }

it's not related to path issues because i can upload small file but when i change my web config to upload large file, in large file i got this error.
what do you think? its not related to :

XML

<system.webServer>
   <security>
       <requestFiltering>
           <requestLimits maxAllowedContentLength="200000000"/>
        </requestFiltering>
   </security>
</system.webServer>

thank you so much.
