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](https://docs.kentico.com/k10/managing-users/user-registration-and-authentication/configuring-windows-ad-authentication.md) must be enabled in IIS and Kentico must be configured to use this type of authentication.
- [IIS WebDAV](http://www.iis.net/download/webdav) is **NOT** compatible with Kentico WebDAV integration. If you have WebDAV enabled in your IIS, Kentico WebDAV integration will not be functional.

## Client-side requirements

- WebDAV in _Edit mode_ 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](https://docs.kentico.com/k10/managing-website-content/configuring-the-environment-for-content-editors/configuring-webdav/installing-and-running-webclient-service.md) topic.

## Limitations

> **Note:** **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.

> **Note:** **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.
