Where Is This PHP.ini File?

I have a 6.1.4 site running and I'm trying to fix the upload max size error. But I can't find this php.ini file that everyone say I need to edit. Could someone please translate this to have file directories in it please? I would really appreciate it.

//

Make sure ffmpeg.exe has permission 777

Also the files folder should have permission 777

Edit your php.ini for the following

max_upload_size = 200M
increase the max execution time
increase max post size.

Thanks Everyone,

Are you on a shared hosting service?  You may not have access to it, and will have to write your technical support for any changes you want made to that file.
