How to hide certain file and directory in Win9x

NTFSD
1

Hi, Gurus.

I searched issues in ntfsd that discuss how to hide file and directory in NT
kernel based OS and now I fortunately realized what I want to do.

Anyway, I need to do same thing in Win9x, but I do not have enough aknowlege
about that.

I think that I need to study ntfsd and IFS kit for this purpose, but I do
not think that I have enough time to do that (again, sorry).

Could you please give me pointer to let me study about that?

Thanks,
Hideyuki Inamasu.

There is no IFS kit for w9x and you hardly get help here as the problem is off topic (guess why is this list named NTFSD :). Fortunately, things can be (it depends…) much easier in w9x. There is standard support for IFS hooking; search for IFSMgr_InstallFileSystemApiHook. As for documentation, some is in the w9x DDK, some can be found in Walter Oney’s System Programming for w95 and probably the best info is in the Stan Mitchell’s Windows 95 File System book. However, these books are probably out of print nowadays and also, some info can be obsolete and not quite valid for w98 Whatever Edition. Also note no of these book shows exactly what do you want to do. Instead, they provide necessary background.

The best thing you can probably do is to use Google and search (mainly groups) for above mentioned API. You can find discussions and probably also examples. Using IFS hooks isn’t very hard unless you need something unusual which depends on undocumented info. I used it in few projects but w9x are fortunately obsolete now and I’m trying to forget such a mess ever existed :wink:
