Hide Overwrite existing files Option of Upload Document Page in SharePoint 2010

Requirement: Uncheck and Hide Overwrite existing files Option in Upload Document Page of SharePoint 2010.

Solution:

If the “Overwrite existing files” option is to be turned off for all uploads, You can locate these lines and Change the Checked=”true” to Checked=”false” in Uploadex.aspx file as below:

1. <asp:CheckBox id=”OverwriteSingle” Checked=”true” Text=<%$Resources:wss,upload_document_Overwrite_file%>” runat=”server” />
2. <asp:CheckBox id=”OverwriteMultiple” Checked=”true” Text=<%$Resources:wss,upload_document_Overwrite_version%>” runat=”server” />

Alternatively, let’s set this option only for the specific site. 

• Login to your SharePoint Web Front End Server, Navigate to: “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\template\layouts” folder
• Make a backup of the “Uploadex.aspx” file and open it in Notepad.
• Search for text </asp:Content> from the top and Insert the below code in it.
• Save and close the uploadex.aspx file. Repeat these steps in all your web front end servers if you have more than one.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
 $(document).ready( function () {
 if(location.href.indexOf('globalfunctions/credit/_layouts/Upload.aspx') >= 0) {

            $("input[id$='OverwriteSingle']").removeAttr('checked');
            $("input[id$='OverwriteSingle']").hide();
            $("label[for$='OverwriteSingle']").hide();
            $("a[id$='UploadMultipleLink']").hide();

      }
 });   
</script>

My requirement is to hide overwrite existing files and upload multiple files options for only a particular subsite, so I’ve wrapped the code inside the “IF” condition. Here is the result of the hidden overwrite existing files option and multiple upload links on the upload page:
