How to find the Extended Content Type of a file

Answer

To configure a specific action for such file types, which are not included by default in the GFI WebMonitor file-type list, perform the following steps:

1. Locate the content-type of the specific file-type
2. Configure GFI WebMonitor to block or scan web downloads with the same content-type

Step 1: Locate the content-type of the object being downloaded

To check the exact content-type of the download using the following procedure in GFI WebMonitor 2015 and newer:

1. Browse to the HTTP web site where the file is located
2. Download the file
3. Open the GFI WebMonitor Console
4. Select Dashboard -> Activity -> Websites/Applications 
5. When the file is downloaded, click Refresh and locate the downloaded file in the URL field. If there are a lot of entries in the list, search for the URL of the downloaded file
6. In the Status field, the content-type of the downloaded file can be verified
   • Example: application/x-ms-wmv is indicative of a *.wmv file

To check the exact content-type of the download, use the following procedure within GFI WebMonitor 2013 and earlier:

1. Browse to the HTTP web site where the file is located
2. Download the file
3. Open the GFI WebMonitor Console
4. Expand Monitoring -> Past Connections 
5. When the file is downloaded, click Refresh and locate the downloaded file in the URL field. If there are a lot of entries in the list, search for the URL of the downloaded file
6. In the Status field, the content-type of the downloaded file can be verified
   • Example: application/x-ms-wmv is indicative of a *.wmv file

Step 2: Add the content-type to the GFI WebMonitor Console:

1. From the GFI WebMonitor Console, expand Web Security Edition 
2. Select Download Control Policy or Virus Scanning Policy, and select the appropriate node
3. Select the appropriate Policy and click the Edit icon
4. For Download Control Policies, select the Download Control tab. For Virus Scanning Policies, select the Virus Scanning tab.
5. Click Add Content-type 
6. In the Content-Type field, add the new content-type. For example: application/x-ms-wmv .
7. Click the Add button and click on Save Settings to apply the changes
