CEP engine extension API to check for file existence

Hi All,

I am looking for an API (CEP FS) which checks a file is exist or not. I couldn't find such inside CEP fs library. I am referring to cep.fs object.

Note: I don't want to use JSX here as that would be asynchronous.

Premiere Pro version: 11.1.0

Extension Type: Panel

Thanks & Regards,
