I'm using MKDir to create a file in a folder. When creating a file, the file name is saved with a random generated 16-digits Alpha-Numeric (i.e. DS1O-Q7LN-X7MP-EJA8) name. The code below checks for a specific file, however How can i check if there is a 16-digits Alpha-Numeric file exist?

Code:
Function FileExists(FilePath As String) As Boolean
Dim TestStr As String
    TestStr = ""
    On Error Resume Next
    TestStr = Dir(FilePath)
    On Error GoTo 0
    If TestStr = "" Then
        FileExists = False
    Else
        FileExists = True
    End If
End Function
 

Excel Facts

Square and cube roots
The =SQRT(25) is a square root. For a cube root, use =125^(1/3). For a fourth root, use =625^(1/4).
You want to check if any 16 character filename exists in a given folder?

Code:
[color=darkblue]Function[/color] FileExists(FilePath [color=darkblue]As[/color] [color=darkblue]String[/color]) [color=darkblue]As[/color] [color=darkblue]Boolean[/color]
    
    [color=darkblue]If[/color] Right(FilePath, 1) <> "\" [color=darkblue]Then[/color] FilePath = FilePath & "\"
    
    FileExists = Len(Dir(FilePath & "????-????-????-????.*")) > 0
    
[color=darkblue]End[/color] [color=darkblue]Function[/color]

If a file exist in the described format above, How can I insert the file name in cell? I tried the code below, but it not entering the correct file name.

Code:
Range("A1") = Len((Dir(OPath) & "????-????-????-????.*"))
