Large File Upload in IIS<\/h2>\n
\n

By default, IIS web server allows for limited file size to be uploaded to the web server. For IIS 6 and IIS 7, the default maximum file upload size is 4 MB and 28.6 MB respectively. IIS 7 returns a 404 error (HTTP Error 404.13 – CONTENT_LENGTH_TOO_LARGE) if someone uploads something larger than 30MB. In order to allow for larger file size uploads, a few server changes are required.<\/p>\n

This tutorial is designed for IIS 7.0+. For 5.0 and 6.0, please check here<\/a>. For Debugging guidelines, please click here<\/a>.<\/p>\n

You have 3 available options to increase the file upload limit:<\/p>\n

1. Modify the maxAllowedContentLength setting in the web.config<\/h3>\n

You can increase the maximum file size by modify the\u00a0maxAllowedContentLength<\/a>\u00a0setting in the web.config file:<\/p>\n

\r\n\r\n\r\n\r\n<\/requestFiltering>\r\n<\/security>\r\n<\/system.webServer><\/pre>\n
With the above maxAllowedContentLength, users can upload files that are 2 GB in size. This setting will work right away without restart IIS services.<\/p>\n
2. Edit the request filtering feature settings and the request limits using IIS manager<\/h3>\n
    \n
  1. Open IIS Manager.<\/li>\n
  2. Select the website that you want to configure.<\/li>\n
  3. Make sure you are in Features View per the button at the bottom of the manager.<\/li>\n
  4. Select Requests Filtering and open it by double-clicking the icon. The Request Filtering pane displays.<\/li>\n
  5. From the Actions pane on the right hand side of the screen click Edit Feature Settings… link. The Edit Request Filtering Settings window displays.<\/li>\n
  6. In the Request Limits section, enter the appropriate Maximum allowed content length (Bytes) and then click the OK button.<\/li>\n
  7. Restart IIS.<\/li>\n<\/ol>\n
    <\/p>\n
    <\/p>\n
    3. Manually edit the ApplicationHost.config file<\/h3>\n
      \n
    1. Click\u00a0Start<\/strong>. In the\u00a0Start Search<\/strong>\u00a0box, type\u00a0Notepad. Right-click\u00a0Notepad<\/strong>, and then click\u00a0Run as administrator<\/strong>.<\/li>\n
    2. On the\u00a0File<\/strong>\u00a0menu, click\u00a0Open<\/strong>. In the\u00a0File name<\/strong>\u00a0box, type\u00a0%windir%\\system32\\inetsrv\\config\\applicationhost.config, and then click\u00a0Open<\/strong>.<\/li>\n
    3. In the ApplicationHost.config file, locate the\u00a0<\/strong>\u00a0node.<\/li>\n
    4. Remove the\u00a0maxAllowedContentLength<\/b>\u00a0property. Or, add a value that matches the size of the Content-Length header that the client sends as part of the request. By default, the value of the\u00a0maxAllowedContentLength<\/b>\u00a0property is 30000000.\n
      For example, modify the following configuration data inside the  section.<\/p>\n
      \n
      \" \/><\/pre>\n<\/div>\n<\/li>\n
    5. Save the ApplicationHost.config file.<\/li>\n<\/ol>\n
      Debug Large File Upload<\/h3>\n
      If you have successfully modified the requestLimits attribute, maxAllowedContentLength, but still cannot upload large files (over 30mb), please check the IIS Large File Upload Debugging Guidelines<\/a>.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
