I am already writing a file to a folder, but if a previous version of that same file exists it simply overwrites the old one.
How do you determine if a file already exists in a certain folder? For example: If I want to write a file called Test1.txt to a certain directory, how do I check if that file already exsits there before actully writing the new file to that directory? If the file does exist I would like to keep that file there and add this new one but add a (1) behind the file.

Thanks a lot
Michael

Function FileExists(lzFileName As String) As Boolean
On Error GoTo ErrorHandler
FileExists = (GetAttr(lzFileName) And vbDirectory) = 0
ErrorHandler:
End Function

returns true if File exists

What does it mean to be "Always On"?

Hi
To check files on LAN too:

Private Declare Function PathFileExists Lib "shell32" Alias "#45" (ByVal sPath As String) As Boolean
Private Declare Function PathIsDirectory Lib "shell32" Alias "#159" (ByVal sPath As String) As Boolean

Cheers
