=Overview=
Sense/Net by default allows files of size 8MB to be uploaded via the built-in upload control, and 100MB (from versions above 6.1.1) to be uploaded via [[Webdav|webdav]]. This how-to describes how to change these default settings.
{{info|In case you are working with large files, regularly updating those can be slower than uploading new ones. In this case please consider using the [[How to enable FILESTREAM in Sense/Net|FILESTREAM]] feature.}}

=Steps=
==1. Set property of upload control==
The upload control defines a property that sets the uploadable file size limit. The control markup containing the upload control in the default install can be found here:

<source lang="text">
/Root/System/SystemPlugins/Portlets/IntraUploadDialog.ascx
</source>

The markup contains an ''sn:listviewupload'' element, that has a '''file_size_limit''' property. The following markup shows how to configure the upload control to enable files of 100MB to be uploaded via the upload control:

<source lang="asp">
    <sn:listviewupload id="FileUploader" runat="server" cssclass="sn-dialog-upload" flashurl="/Root/Global/scripts/swfupload/swfupload.swf"
        uploadurl="/UploadProxy.ashx" begin_upload_on_queue="true" file_queue_limit="0"
        file_size_limit="102400" file_types="*.*" file_types_description="All files" file_upload_limit="0"
        allowothercontenttype="true" designmode="dialog" button_placeholder_id="spanButtonPlaceholder"
        minimum_flash_version="9.0.28" button_window_mode="transparent" button_cursor="-2"
        button_width="150" button_height="22" />
</source>

==2. Change web.config settings==
The upload control uses chunked uploading and thus the above settings are adequate for uploading files via the built-in upload control. However when uploading files via [[Webdav|webdav]] the request length could exceed a limit and thus the IIS will deny these requests. This limit can be configured in the web.config with the following settings:

<source lang="xml">
  <system.web>
    <!-- Enable large file upload via webdav/upload. Max file size in KB. -->
    <httpRuntime maxRequestLength="102400" requestLengthDiskThreshold="102400" requestValidationMode="2.0" />
</source>

and:

<source lang="xml">
  <system.webServer>
    <security>
      <requestFiltering>
        <!-- Enable large file upload via webdav/upload. Max file size in bytes. -->
        <requestLimits maxAllowedContentLength="104857600" />
</source>
