Policy
Disable download file type extension-based warnings for specified file types on domains
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
You can enable this policy to create a dictionary of file type extensions with a corresponding list of domains that are exempted from file type extension-based download warnings. This exemption lets enterprise administrators block file type extension-based download warnings for files that are associated with a listed domain. For example, if the "jnlp" extension is associated with "website1.com", users can't see a warning when downloading "jnlp" files from "website1.com" but can see a download warning when downloading "jnlp" files from "website2.com". Files with file type extensions specified for domains identified by this policy are still subject to nonfile type extension-based security warnings such as mixed-content download warnings and Microsoft Defender SmartScreen warnings. If you disable this policy or don't configure it, file types that trigger extension-based download warnings show warnings to the user. If you enable this policy: * The URL pattern should be formatted according to https://go.microsoft.com/fwlink/?linkid=2095322. * The file type extension entered must be in lower-cased ASCII. The leading separator shouldn't be included when listing the file type extension; so, list "jnlp" should be used instead of ".jnlp". Example: The following example value prevents file type extension-based download warnings on swf, exe, and jnlp extensions for *.contoso.com domains. It shows the user a file type extension-based download warning on any other domain for exe and jnlp files, but not for swf files. [ { "file_extension": "jnlp", "domains": ["contoso.com"] }, { "file_extension": "exe", "domains": ["contoso.com"] }, { "file_extension": "swf", "domains": ["*"] } ] While the preceding example shows the suppression of file type extension-based download warnings for "swf" files for all domains, applying suppression of such warnings for all domains for any dangerous file type extension isn't recommended due to security concerns. It's shown in the example merely to demonstrate the ability to do so. Example value: [ { "domains": [ "https://contoso.com", "contoso2.com" ], "file_extension": "jnlp" }, { "domains": [ "*" ], "file_extension": "swf" } ]
