If you use the intrinsic VB Dir$ function to check for the existence of a certain file, then subsequently try to remove the directory where the file is found using the VB RMDir statement, you get the error 75, "Path/File access error." This error occurs even if you kill the file prior to removing the directory.
You can see the problem if you manually create a directory and file with the names c:\dummy\bla-bla.txt. Then try to go step-by-step through this sample code to see what's going on:
Private Sub Command1_Click()
If Dir$("C:\dummy\bla-bla.txt") = "" Then
'do nothing, file is not found
Else
'kill the file and remove the directory
Kill "C:\dummy\bla-bla.txt"
RmDir "C:\dummy"
End If
End Sub
