# Change the file size limit on evidence uploads to WebDAV

When a WebDAV server is set up using Microsoft Internet Information Services (IIS), the default maximum allowed content length is 28 MB. You can increase this value to allow upload of files greater than 28 MB. However, the recommended value to allow upload of files is 40 MB.

You must set a value greater than the **Maximum evidence file size** limit set in **Policy Settings** → **Shared Storage and Evidence**. There is a maximum size limit of 250 MB for files uploaded to the Registered Document Repository.

1. In Microsoft Internet Information Services Manager (IIS), select your WebDAV folder and click **Request Filtering**.
2. In the **Actions** menu on the right, click **Edit Feature Settings**.
3. The default value in the **Maximum allowed content length (bytes)** field is set to 28 MB. Type your preferred limit for evidence files upload. The limit is calculated in bytes.

The new file size limit for your WebDAV storage is set in IIS.
