Adding modules to cleanmgr.exe

[rbdietz]

I recently discovered that new items can be added to Windows' Disk Clean up utility (cleanmgr.exe) by simply adding a registry key with appropriate values. The details are buried at Creating a Disk Cleanup Handler.I used term buried because the vast bulk of page is concerned with writing a new cleanup handler from scratch. Skip that and look for the - two paragraph long - "Using the DataDrivenCleaner Object" section near the bottom of the page. Then study the table of registry values that proceeds it.Here are a few examples to show just how easy this is. (Copy and paste into notepad. Save as a .reg file. Then double click on the file.)Remove seldom used items from Windows Prefetch

Windows Registry Editor Version 5.00 ; Remove seldom used items from Windows Prefetch [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Trim Prefetch]@="{C0E13E61-0CC6-11d1-BBB6-0060978B2AE6}""Display"="Trim Prefetch""Description"="Trims items from prefetch which haven't been used in the last 3 weeks""FileList"="*.pf" ; Only prefetch files will be deleted. "CSIDL"=dword:00000024 ; dword:00000024 corresponds to the %SYSTEMROOT% folder "Folder"="Prefetch" ; The CSIDL and Folder entries get combined; on most systems CSIDL + FOLDER = C:\Windows\Prefetch "LastAccess"=dword:00000015 ; Ignore files that have been accessed within the last three weeks.; Prefetch is suppose to be for frequently used items.; If we haven't used the item in over three weeks, it may not make sense to prefetch it. "StateFlags0000"=dword:00000002"StateFlags"=dword:00000000

Clean %windir%\Temp which XP's Disk Cleanup normally leaves untouched.

Windows Registry Editor Version 5.00 ; Cleans %windir%\Temp which XP's Disk Cleanup normally leaves untouched.

Thanks rbdietz. It would be interesting if someone could develop an object or series of objects that parallel Fred Langa's batch Cleanup jobs.

I emailed Fred the info before posting it to this forum. :)I don't currently have a Windows 98 system to test on. And I have some doubts about the CSIDL parameter working on such systems. If it does work, the following modules could be made more general.FWIW here are four modules that could replace Fred's basic Cleanup.bat file on Win98/ME or WinXP with the indicated edits.
