Internet Explorer compares several indicators for the type of a file received from a web server: the file name extension, the HTTP \u003Ccode>Content-Type\u003C\u002Fcode> and \u003Ccode>Content-Disposition\u003C\u002Fcode> headers, and the type detected by examining the file signature.\u003C\u002Fp>\n\u003Cp>When the policy is enabled, these indicators must be consistent. For example, if Internet Explorer detects executable content while the server identifies the file as \u003Ccode>text\u002Fplain\u003C\u002Fcode>, it does not rely solely on the apparently less dangerous server-supplied type. Files with conflicting type information are renamed and moved to the Internet Explorer cache.\u003C\u002Fp>\n\u003Cp>When the policy is disabled, Internet Explorer does not require consistent MIME information for files received by these processes.

Disabling the policy removes this additional consistency check for the covered processes. This increases the risk that incorrectly declared content will be handled according to misleading type information.\u003C\u002Fp>\n\u003Cp>This feature is neither antimalware scanning nor a general download block.
