Finding files

[Innofin]

Can anyone tell me how to find out how many files I hae on a PC wih the name, let's say, "File.mdb"?

I used the SearchTreeForFile, but this only returns the path to the first occurance. I want to be able to list all occurances of a file.

Any ideas?

Hi there Innofin,
using the FSO might be to slow, but anyways, this is one way of doing it

Option Explicit
 
Private Function FoldersWhereFileExists(ByVal sFolder As String, sFileName As String) As String
    Dim fso As New FileSystemObject
    Dim f As Folder
    Dim fldr As Folder
    Dim fil As File
    Dim sFoldersContainingFiles As String
    'set start folder
    Set fldr = fso.GetFolder(sFolder)
        For Each fil In fldr.Files
            If UCase(fil.Name) = UCase(sFileName) Then
                sFoldersContainingFiles = sFoldersContainingFiles & fldr.Path & vbCrLf
                Exit For
            End If
        Next fil
        
        FoldersWhereFileExists = sFoldersContainingFiles
        
        'in order to retrieve all the subs in the subs in the subs.... uh... _
        'we have to call 'ourselfs' until there are no more subfolders left...
        If fldr.SubFolders.Count > 0 Then
            For Each f In fldr.SubFolders
                FoldersWhereFileExists = FoldersWhereFileExists & FoldersWhereFileExists(f.Path, sFileName)
            Next f
        End If
End Function
 
Private Sub Command1_Click()
    MsgBox FoldersWhereFileExists("C:\", "testigs.txt")
End Sub

i've attached an example from APIGuide that i've modified slightly for you (zip file).

this is the code in the main form though:

'Create a form with a command button (command1), a list box (list1)
'and three text boxes (text1, text2, text3).
'Type in the first textbox a startingpath like c:\
'and in the second textbox you put a pattern like *.* or *.txt
