CEMon

the author of this app says:

CEMon is a driver / application combination that monitors and displays flush memory activity of Windows CE operating system, both on logical and physical levels. CEMon allows a user of a handheld PC to see how Windows CE works, how applications use files and DLLs, and track down problems in system or application configuration. All of these features are similar to Filemon for Windows NT/9x, but the architecture of CEMon and its source code are quite different from those of Filemon for Windows NT/9x.
