Can anybody tell me what is the purpose of the file $_hpcst$.hpc which is found in my Windows XP pro c:\Windows folder

I'm not having any particular problem with it, but I don't know whether it is a necessary file or not.

    It seems this file is related to group policies. ( )
    Is workstation member of a domain?

    Yes - it is on a corp network on a domain.  I guess I shouldn't delete it then.  maybe I'll try renaming it temporarily to see what happens.  Seems odd, though, that there isn't much information about it anywhere.

    I'll hang out a bit longer before I close this and award points, to see if anyone comes up with a more definitive answer.

    Even though the question has been closed, I'll add a bit more information in case anybody is interested.

    The file you mentioned is also used by Microsoft Windows CE Services, more specific by Microsoft ActiveSync when performing file conversions between Pocket PC formats (PWI) and Windows formats (RTF).

    In this context, it is created by a certain function in ceutil.dll before the conversion actually takes place. It is then mapped as a memory mapped file and further accessed as a memory area by all Pocket PC to RTF conversion DLLs. I guess it is used as a global storage pool to exchange information between various ActiveSync modules.

    Deleting it does no harm. It will be created automatically when you'll do your next conversion or synchronization with your Pocket PC. Unfortunately Microsoft didn't include a delete routine in their clean-up code, so you'll end up with this file in your Windows folder again.

    Hope this does add a bit of information on this topic.
