Remote API (RAPI)

A version of this page is also available for

Windows Embedded CE 6.0 R3


The Remote API (RAPI) library enables applications that run on a desktop to perform actions on a remote Windows Mobile device. The functionality that RAPI provides includes the ability to manipulate the file system on the remote device, including the creation and deletion of files and directories. RAPI functions can be used to create and modify databases, either in the device's object store or in mounted database volumes. RAPI applications can also query and modify registry keys as well as launch applications and invoke methods on the remote device. Although most RAPI functions are duplicates of functions in the Windows Embedded CE API, a few new functions extend the API. Use these functions to initialize the RAPI subsystem and enhance performance of the communication link by compressing iterative operations into one RAPI call.


There is an updated version of this library called Remote API 2 (RAPI2) that has expanded functionality and enhanced performance. Although RAPI is still supported, developers are strongly recommended to use the newer RAPI2 library.
