You can enable this policy to create a dictionary of file type extensions with a corresponding list of domains that will be exempted from file type extension-based download warnings. This 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 would not see a warning when downloading "jnlp" files from "website1.com", but see a download warning when downloading "jnlp" files from "website2.com". Files with file type extensions specified for domains identified by this policy will still be subject to non-file type extension-based security warnings such as mixed-content download warnings and Safe Browsing warnings. If you disable this policy or don't configure it, file types that trigger extension-based download warnings will show warnings to the user. If you enable this policy: * The URL pattern should be formatted according to https://chromeenterprise.google/policies/url-patterns/. * The file type extension entered must be in lower-cased ASCII. The leading separator should not be included when listing the file type extension, so list "jnlp" should be used instead of ".jnlp". Example: The following example value would prevent file type extension-based download warnings on "exe" and "jnlp" extensions for *.example.com domains, and on "swf" extensions for all domains. It will show 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": ["example.com"] }, { "file_extension": "exe", "domains": ["example.com"] }, { "file_extension": "swf", "domains": ["*"] } ] Note that 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 is not recommended due to security concerns. It is shown in the example merely to demonstrate the ability to do so. If this policy is enabled alongside DownloadRestrictions, then the exemptions to file type extension-based warnings specified by this policy take precedence over a DownloadRestrictions setting that would block dangerous file types. The exemptions specified by this policy only apply to the "block dangerous file types" behavior specified by values 1 and 2 of DownloadRestrictions. For example, if this policy specifies an exemption for "exe" downloads from "website1.com", and DownloadRestrictions is set to block malicious downloads and dangerous file types (value 1), then "exe" downloads from "website1.com" will be exempt from file type extension-based blocking but will still be blocked if they are malicious. More information about DownloadRestrictions can be found at https://chromeenterprise.google/policies/?policy=DownloadRestrictions. See https://chromeenterprise.google/policies/?policy=ExemptDomainFileTypePairsFromFileTypeDownloadWarnings for more information about schema and formatting. Example value: [ { "domains": [ "https://example.com", "example2.com" ], "file_extension": "jnlp" }, { "domains": [ "*" ], "file_extension": "swf" } ]

These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
