Import sub folder Proto files

[Novice User]

Currently I've a single proto3 file, lets call it TopLevel.proto

package myprotos.protobuf; 

message top { 

  string name; 

}

I want to create a new folder w/ some proto files, lets call folderA with different proto

Inside.proto

package myprotos.protobuf.folderA; 

message Inner { 

 long value; 

}

When in PyCharm, I am importing Inner in TopLevel.proto it is unable to find :

package myprotos.protobuf; 

import "folderA/Inside.proto"; 

message top { 

      string name; 

       Inner inner; 

}

Any suggestion on how to import the subfolder proto files?
