determine whether a path is a directory or a file

    does any one here know of a good way to to determine whether or not a
    given path is a directory (e.g., "c:\mydir") or a file (e.g., "c:\mydir

    i started attacking this problem by using filesystemobject to check
    whether or not a directory existed for the path. if so, it was a
    directory path. if not, i checked to see if a file existed for it. if
    so, it was a file path. this code is shown below:

    function GetPathType(byval sPath)
    const INVALID = 0
    const DIRECTORY = 1
    const FILE = 2

    dim iResult : iResult = INVALID

    dim fso : set fso = CreateObject("Scripting.FileSystemObject")

    if fso.FolderExists(sPath) then
    iResult = DIRECTORY
    elseif fso.FileExists(sPath) then
    iResult = FILE
    end if

    set fso = nothing

    GetPathType = iResult
    end function

    but, what if i need to determine a path type regardless of whether or
    not the directory or file currently exists?

    any ideas out there?

    thanks in advance

  2. Not strictly possible.

    A file with no extension would as a string look identical to a folder path.
    Also a dot in a folder name is not illegal.

    However it's reasonable to assume the file will have a short extension

    Function ProbablyAFile(sPath)
    Dim rgx : Set rgx = New RegExp
    rgx.Pattern = "\.[^\\]{,5}$"
    ProbablyAFile = rgx.Test(sPath)
    End Function
