SharePoint 2010 : How to Enable Uploading Multiple Documents Functionality

SharePoint 2010 : How to Enable Uploading Multiple Documents Functionality

 This topic is a how to.
Please keep it as clear and simple as possible. Avoid speculative discussions as well as a deep dive into underlying mechanisms or related technologies.

As a SharePoint Power-User or a SharePoint Administrator depending on responsibility policy made, you sometimes are asked regarding uploading multi- document. Or getting involved to SharePoint community, you would have seen a lot of questions as to grayed Upload Multiple Document functionality.

When opening SharePoint document library, you would be asked to run Microsoft Office 2010 component by Internet Explorer automatically.

After allowing, I’ve checked and noticed the ActiveX Control called STSUpld.UploadCtl ( in the Manage Add-ons option is enabled.

After that, check Upload Multiple Document functionality, you would see that it works well.

If you disable STSUpld.UploadcCtl, Upload Multiple Document functionality will be grayed out.

According Microsoft, this control is defined in the STSUPLD.dll, a dynamic-link library (DLL) that is installed on the client computer in the %ProgramFiles%\Microsoft Office\Office14\ directory during Microsoft Office 2010 Setup.

In my humble opinion, this basically means if your computer doesn’t have STSUPLD.DLL stored in %ProgramFiles%\Microsoft Office\Office14\ directory, you can not use Upload Multiple Documents functionality.

If you are using Microsoft Office 2007 on WSS 3.0 or MOSS 2007 environment, STSUPLD.DLL is stored in %ProgramFiles%\Microsoft Office\OFFICE12\ directory.

In a nutshell, if your end-user can not upload multiple documents into a document library, make sure the following things at least:

Supported to above IE7

Update: I’ve done a test with Office 2013 on SharePoint 2010. The STSUPLD.DLL is still kept in Office 2013 so the functionality continues rocking! Check the below image out:

  • Guys,

    I've checked Office 2013 with SharePoint 2010. It still works. I've just updated.

  • After I dump the dll file into Office directory, how does it enable STSUpld.UploadCtl? My problem is that after I placed the DLL, ther is no add-on detected in IE. Do i need to do anything to "activate" STSUpld

  • This is very use full article

  • I'm having the same issue as elfyelfy on more and more workstations around the office... with SP2010 and Office 2013, the multi-upload button is there for a while and then disappears.  The DLLs are still enabled.  Disabling them and re-enabling as well as re-installing Office doesn't make it come back.  :(
