How to use FileDateTime function in VBA?

The `FileDateTime` function in VBA is used to return the date and time when a file was created or last modified. This function takes a single argument, which is the path to the file.

Here’s the syntax for `FileDateTime`:

FileDateTime(pathname)

`pathname`: A string expression that specifies a file. The `pathname` can include the directory or folder, and the drive.

Below is an example of how to use the `FileDateTime` function in VBA:

Sub ExampleFileDateTime()
    Dim strFilePath As String
    Dim dtFileCreated As Date
    
    ' Specify the path to the file
    strFilePath = "C:path_to_your_fileexample.txt"
    
    ' Use FileDateTime to get the date and time of the file
    dtFileCreated = FileDateTime(strFilePath)
    
    ' Display the date and time in a message box
    MsgBox "The file was created or last modified on: " & dtFileCreated
End Sub

Note that the `FileDateTime` function will return an error if the file does not exist or the path is invalid. Therefore, it is good practice to check if the file exists before calling this function. You can use the `Dir` function to check if a file exists:

Sub ExampleFileDateTimeSafe()
    Dim strFilePath As String
    Dim dtFileCreated As Date
    
    ' Specify the path to the file
    strFilePath = "C:path_to_your_fileexample.txt"
    
    ' Check if the file exists
    If Len(Dir(strFilePath)) > 0 Then
        ' File exists, get the date and time
        dtFileCreated = FileDateTime(strFilePath)
        
        ' Display the date and time in a message box
        MsgBox "The file was created or last modified on: " & dtFileCreated
    Else
        ' File does not exist
        MsgBox "The specified file does not exist."
    End If
End Sub

Remember to change `”C:path_to_your_fileexample.txt”` to the actual path of the file you want to check.
