file size

Hi all,

We have a filter which should automatically decompress files (if they are compressed) so it works implicitly for all applications. At the moment we have a problem with changing a file size reported by a FS to the uncompressed size.

We modify sizes in IRP_MJ_DIRECTORY_CONTROL and IRP_MJ_QUERY_INFORMATION completion routines but they does not change.

Thank you,
Roman
