An MRP file is an app created for the Mythroad mobile platform used by China Mobile and Cherry Mobile phones. It contains a program, typically a game, and all of the resources required by the program to run. MRP files are similar to .VXP files and may come pre-installed on the phone or may be downloaded from the Internet and installed on the phone.

MRP files are used by China Mobile phones that do not support Java. The program files are typically much smaller than .JAR Java apps, roughly one-third the size. To install an MRP app on a phone, move the file directly to the memory card of the phone using a USB connection. Then, to complete the installation, place the files in the appropriate programs folder with the other MRP files, which may be one of the following folders: Mythroad, Mulgame, Mrapp, Games.
