URL path length restrictions (SharePoint Server 2010)

There is no limit to encoded URLs in SharePoint Server 2010. The limitations are the following:

  • 260 Unicode (UTF-16) code units – the characters in a full file path, not including a domain/server name.
  • 256 Unicode (UTF-16) code units – the characters in a full folder path, not including the file name and the domain/server name.
  • 128 Unicode (UTF-16) code units - characters in a path component, that is, a file or folder name.
  • 260 Unicode (UTF-16) code units – the characters in a full path, including a domain/server name for use with Office clients.
  • 256 Unicode (UTF-16) code units – the characters in a full path including the domain/server name, for use with Active X controls.
Internet Explorer URL length limitations

Internet Explorer also has limitations that are separate from those in SharePoint Server 2010. Even though you make the SharePoint Server 2010 URL path shorter than the limitations, you might experience an Internet Explorer URL length limitation because of added parameters and encoding of the URL. You must use the most restrictive limitation as a guideline for planning URL lengths.

Both Internet Explorer 7 and Internet Explorer 8 have a maximum URL length of 2,083 UTF-8 characters and a maximum path length of 2,048 UTF-8 characters. However, in Internet Explorer 7, under certain circumstances, the effective URL length limitation is 1024 UTF-8 characters, not 2083 UTF-8 characters. For more information about the URL length limits in Internet Explorer, see Microsoft Knowledge Base article 208427, Maximum URL length is 2,083 characters in Internet Explorer (



Unless all of the browsers in the environment are Internet Explorer 8, use the effective limit of 1024 UTF-8 characters.

Resolving URL length problems

There are several ways that you can resolve or mitigate URL length problems in the SharePoint Server 2010 environment. The following list provides suggestions:

  • Upgrade all the end-user browsers to Internet Explorer 8, which has a longer URL length limit.
  • Use shorter names for sites, folders, and documents and control the depth of the site and folder structures to reduce the lengths of URLs.
  • If possible or allowed, use ASCII names for sites, folders, and documents. This will avoid situations where the URL will be lengthened by being encoded.
  • To reduce the risk that the SharePoint Server 2010 end-users will encounter problems because of URL length limitations, we recommend that you apply the following effective limits in the deployment:
    • 256 Unicode (UTF-16) Code units - the effective file path length limitation, including a domain/server name
    • 128 Unicode (UTF-16) Code units - the path component length limitation
