Name: File_Extension (Small code to return the extension of a file from the full path)

Returns:The extension of the file.
Unknown" if it can't find the file's extension.
'
' Assumes:Make a module and copy and paste this into it. Then, make a Button. Double click
on the button. When the code window pops up, put in the following: File_Extension("C:\Your\File
\Here.doc")

Public Function File_Extension(Full_File_Name As String) As String
'File's extension can't be longer than 5
' characters long.

If InStr(StrReverse(Full_File_Name), ".") >= 7 Or InStr(StrReverse(Full_File_Name), ".") <= 1 Then
'If it can't find the extension, it retu
' rns "Unknown".
File_Extension = "Unknown"
Else
'Returns the file's extension.
File_Extension = Mid(Full_File_Name, Len(Full_File_Name) - InStr(StrReverse(Full_File_Name), ".") + 2)
