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.
In Microsoft Internet Information Services Manager (IIS), select your WebDAV folder and click Request Filtering.
In the Actions menu on the right, click Edit Feature Settings.
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.
Add or update MIME types on WebDAV server
Multipurpose Internet Mail Extensions (MIME) is a standard that indicates the format of a file.
Default Microsoft IIS server security policies prevent the download of files that do not match the specified types. Add or update the following file extensions to the MIME type list on the Microsoft IIS server:
Extension: .* | MIME type application/octet-stream |
Extension: .dat | MIME type application/octet-stream |
Extension: .dlpenc | MIME type application/octet-stream |
For information about how to enable Microsoft IIS server to recognize the needed MIME types, see KB96817.
