    Hi All,

    I am doing a wql-select to find a set of files or a completely specified
    filename. My only problem is, if I specify some property-combinations,
    nothing is returned. For example:

    select * from CIM_DataFile where (Drive = 'c:') and (Path = '\\test\\') and
    (Extension = 'txt')

    returns a result, one of them is "c:\test\demo.txt", exactly, what I expect.
    But if I use

    select * from CIM_DataFile where (Drive = 'c:') and (Path = '\\test\\') and
    (Extension = 'txt') and (FileName = 'demo')

    the query executes properly, but returns an empty resultset. If I specify
    the FileName, but not the extension, it works also. The problem occurs only,
    if I specify drive, path, FileName and Extension together. I am currently
    building a wmi-based library, which should be useful under all conditions
    [Ok, I I know and have the full qualified filename, I would use another
    method!]. I use and need WMI for that, because it allows impersonation in
    web-management tools.

    Any help would be great!

    Best regards,
    Manfred Braun
