What do you mean by "files"? Are you referring to files stored on disc, or are you referring to records in an Access table?

Open the cmd window, go to the folder you want to delete the files from and execute the following command:
forfiles -d -7 -c "cmd /c dir @file"
-- or --
forfiles -d -7 -c "cmd /c dir @path"

This will show you the files you want to delete. To actually delete them, do this:
forfiles -d -7 -c "cmd /c del @file"

The -7 is exactly 7 24 hour periods. So if it is 5:00pm and you want to delete a file from 6:00pm 7 days ago, it won't find it. It will find files before 5:00pm 7 days ago.

I highly suggest lookin at the help also by using the command: forfiles /?

Once you get what you want, you can put it in your own bat file also.

Hi COHFL,

Sorry to be a pain, but do you mean to delete *records* in the database which are older than 3 days (files are something different!)?

...In which case a simple SQL DELETE query should do the trick:

DELETE FROM tbl_name WHERE creation_date < getdate()-3;

You can implement this in SQL Query Design View located through the wizard in Access.

The author asked for CODE to do this, not commands to manage this by hand. While a batch file could be used, of course, your solution wouldn't really be Access-friendly.

I appreciate your remarks but i suppose we are both trying to help out this person. It's noone's fault that people do not provide the exact information that we need in order to help them correctly. Ss i said in my previous post, in this case it's better to have multiple answers that solve one problem than having multiple unanswered questions.

Have a sweet day.

I'm sorry for the confusion my question has cause. What im trying to do is to have a routine that went it gets call it goes out and the following:

Private Sub cmdDeleteFiles_Click()
On Error GoTo Err_cmdDeleteFiles_Click

Dim Directory as string
Directory = "C:Windows\Folder\"

'now here i need to loop for all the files that are and stored in Directory once i have them compared them with datetime() and the file datetime creation  and if the day is > than 3 them delete it. otherwise just leave it alone.


Exit_cmdDeleteFiles_Click:
    Exit Sub

Err_cmdDeleteFiles_Click:
    MsgBox Err.Description
    Resume Exit_cmdDeleteFiles_Click
End Sub

I have done this on .Net but MS Access does not behave the same way hence my question.
Help will be greatly appreciated.

perhaps this little function will do the job:
Function delete_old(ByVal Dir_Path As String) As String
Dim Masq_File As String
Dim File_Date As Integer
Dim FDate As Date

Dim MyMonth As String
Masq_File = Dir_Path & "\" & "*.*"
Dir_Result = Dir(Masq_File, vbNormal)
    While (Dir_Result <> "")
    On erro GoTo BadName
    FDate = FileDateTime(Dir_Path & "\" & Dir_Result)
        If (FDate < DateAdd("d", -5, Now())) Then
            Kill Dir_Path & "\" & Dir_Result
        End If
BadName:
    Dir_Result = Dir
    Wend
End Function
