WebDAV requirements and limitations

The following requirements must be met on the server and the client-side in order for WebDAV integration to be functional in Kentico.

Server-side requirements

  • Windows authentication must be enabled in IIS and Kentico must be configured to use this type of authentication.
  • IIS WebDAV is NOT compatible with Kentico WebDAV integration. If you have WebDAV enabled in your IIS, Kentico WebDAV integration will not be functional.

Note that if you want run your website using an application pool set for Classic managed pipeline mode, you need to configure your web.config file.

Client-side requirements

  • WebDAV can be used only in Internet Explorer. No other web browsers are currently supported.
  • Client applications with WebDAV support for particular file types need to be installed on the client machine. For example, Microsoft Office 2003 or higher or Paint and Notepad in Windows 7 support editing of associated file types using WebDAV.
  • Matching (x86) or (x64) versions of both Internet Explorer and Microsoft Office must be installed. In other words, to be able to open documents using WebDAV in Internet Explorer (x86), Microsoft Office (x86) must be installed on the client computer. For Internet Explorer (x64), you need to have Microsoft Office (x64) installed.
  • The WebClient service needs to be installed and running in order for WebDav clients to be able to connect to the server. For more information on how to install and run the service on Windows, see the Installing and running WebClient service topic.


Editable file size limit

By default, WebDAV editing is only functional with files smaller than 50 MB.

In case that a user needed to edit larger files using WebDAV, they would need to go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters in their Windows registry and adjust the FileSizeLimitInBytes key to the required value.

Forbidden characters in file names

WebDAV does not support uploading and editing of files whose names contain the following characters: %, &, +. Uploading and editing of such files using WebDAV may result in unwanted behavior and is not recommended.
