iPhone / Utilitaires

Welcome to RMSA. Thank you very much for using our APP, our team will continue to optimize the app, aiming to provide you with better service and experience.
The purpose of the file extension is to let the system decide which software to run when the user wants to open the file.
The APP mainly provides computer common file extensions, designed to help users understand and learn file extensions. Users can learn file extensions by doodling or drawing: learn extension characters and the definition of file extensions. In this way, the purpose is to publicize the file extension, so that more users understand and learn.
