Hi @raspopov , Thanks for your kind response ,Actually i want to add new extension and want to change the option "How should this file be indexed" filter for any file type from "properties only" to "properties and content" as my requirement is to index all file content , as i am searching within content of all files in my project .

So kindly suggest how can i implement "Add new extension" and change "How should this file be indexed" to "properties and content" for all file type .

I'm not quite sure I understand. Are you looking to do it programmatically? Otherwise, I'm afraid I don't understand why it can't be done in the standard way as in the picture above.

yes i need to do it programmatically with windows searchapi .

I think to enable content filtering, you need to set the default value of the HKEY_CLASSES_ROOT\.ext\PersistentHandler registry key to the filter CLSID, for example {5E941D80-BF96-11CD-B579-08002B30BFEB} for a simple text content filter (Windows 10 "Plain Text persistent handler"), or remove the key entirely to revert to properties only.
