How can I run a Windows built-in disk defragmenter from my MFC app?

My app creates/deletes large numbers of large files, soI would like it to automatically defragment the hard drive, when it finds appropriate. The defrag should run with no user assistance.

You can use WinApi WinExec funtion to call defrag.exe:

::WinExec("defrag c:", SW_HIDE);

Also you can use WinAPI ShellExecute() function.

You could use the file system control commands to write your own simple defragger as outlined here with source code: http://www.sysinternals.com/ntw2k/info/defrag.shtml

Or you could use WMI, using the Win32_Volume object and the DefragAnalysis and Defrag methods and the Win32_DefragAnalysis object to determine if you need to defragment, and then actually do it.

Defragging can take hours and significantly impacts the performance of the system when it runs,  I'm not sure it's such a good idea to do this automatically, unless the user has requested that it be done that way.

WinExec("c:\\windows\\system32\\dfrg.msc", SW_MAXIMIZE); should bring up the defrag program for you
