my filter driver is able to handle IRP_MJ_QUERY_INFORMATION requests
properly and present to user apps file sizes less my own footer. however,
winzip uses IRP_MJ_DIRECTORY_CONTROL to query file sizes as well and
compares this with the sizes it gets from IRP_MJ_QUERY_INFORMATION. it will
not zip if the two sizes are different.
how can i safely trap and return the file size less my footer at
IRP_MJ_DIRECTORY_CONTROL? the file obj for this request is not for the file
but for the directory…
i tried to use zwcreate, followed by zwqueryinformationfile, then zwclose.
but the system hangs after some time, anyone knows why?
