visual c++ - How to find & close all open file handles on a removable drive (before ejecting) -

-

I am trying to remove a (virtual) removable drive, and it fails because some file handles Are open, perhaps Explorer windows What is the best way to get all the open handles on files on that drive and turn it off?

Is it also possible (in user mode) to find any process that runs from that drive, so I can warn with the name of the user name process?

Ideally I want to do this in the user-mode app instead of requiring admin privileges.

I am using VC ++ in Visual Studio 2005, in an MFC app, but any language samples will be welcomed!

The utility can search for open handles, but I do not know if it is possible without high privileges Or can not. I am able to collect it, it uses the "display counter" API.

I think this article what you need, tell the running processes, calculate the handle for each one, look for a file refers to a path on the drive in question:

The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
