Using VBA to get a File’s Last Modified Date

It is sometimes useful to know the date and time a file was last modified.  this is particularly useful if you have a folder full of similar files and need to use the latest copy.

Today the code I’m going to share below enables you to pass a file address into a function which will return the date and time it was last saved.  The example below passes a file address to the function, which returns the modified date, this is then displayed in a message box.

The function requires a reference to Microsoft Scripting Runtime within the VBE.

Sub MyMacroRoutine()
    Dim ModDate As Date
    ModDate = FileLastModDate("C:\YourFileAddressGoesHere")
    MsgBox ModDate
End Sub

Function FileLastModDate(strFileAddress As String) As Date
' In the VBE, set a reference to Microsoft Scripting runtime

    Dim fso As Scripting.FileSystemObject
    Dim fsof As Scripting.File
    Dim strPath As String

    Set fso = New FileSystemObject
    strPath = strFileAddress
    Set fsof = fso.GetFile(strPath)
    With fsof
        FileLastModDate = .DateLastModified
    End With

    Set fso = Nothing
    Set fsof = Nothing

End Function
