Process.get_open_files() does not support network handles

[mrjefftang]

On Windows, psutil_get_open_files returns a list of file names in a raw format such as:
\Device\HarddiskVolume1\Windows\systemew\file.txt

However for a network file, the raw format looks like this:
\Device\Mup\sharename\path\to\file.txt

These filenames are split to take the first 2 items "\Device\HarddiskVolume1" or "\Device\Mup" and passed to QueryDosDevice.

If QueryDosDevice fails, it just returns blank and the following call to isfile_strict will fail so the filename will not return.

There are 2 cases to consider:
1 - The network drive is mapped to a drive letter e.g. Z:\path\to\file.txt
2 - The network drive is not mapped: \sharename\path\to\file.txt

I can reproduce the issue by putting psutil GIT cloned directory in a shared folder (Z:\) and I see exactly the behavior you describe. In my case the file looks like "\VBOXSVR\psutil\file".
That kind of path is not usable by python (e.g. open() won't work). We would need the actual drive letter to which it is mapped, something like "Z:\VBOXSVR\psutil\file", but I'm not sure how to do that (QueryDosDevice does not resolve it).

Just ran into this issue. I can successfully get open files on local drive but completely breaks when trying network-mapped ones.

Is there any other alternative to get network-drives to work?
