Cab Making

[Rhodium500]

Is it possible to make a cab install files and also delete one file on the phone? I have WinCE cab but I don't know how or if it is easy to make the cab delete a file.
I have to delete an old database file for a new program to work properly.

Am I missing something. I don't see my question answered in your link.

you can do it with a provxml, add this to "pre XML" or "post XML" section, depending on needs, on the "cab information" page in wincecab manager

<characteristic type="FileOperation">
	<characteristic type="*full path of file to delete*" translation="install">
		<characteristic type="Delete">
			<parm name="ForceDelete" /> 
		</characteristic>
	</characteristic>
</characteristic>

Thanks for the help. does this look right.

<characteristic type="FileOperation">
    <characteristic type="\Application Data\HTC\databases\forecast_cache.db" translation="install">
        <characteristic type="Delete">
            <parm name="ForceDelete" /> 
        </characteristic>
    </characteristic>
</characteristic>

looks right to me, try it out and make sure

It didn't work. What should I try now?

from what i know that isn't possible...you have to create a SETUP.DLL in WinCE manager to delete files, and creating these DLLs isn't exactly easy either since you have to write the functions in C++

yes it is possible, check out my cab from the new sprint navigation thread. it does exactly this. it deletes the old preferences file before installing the new stuff. the file may be in use hence is why you cannot delete or override it. try turning off manila then installing your cab.

you're right it is possible, just tested it..wonder it it's possible to move stuff this way? a lot easier than dealing with dlls that's for sure!
