I need to loop through the files in a given folder in descending order of 'Last Modified Date'.
In the first iteration of the loop I need to be able to open the most recently modified file for reading and close it. In the second iteration, I need to be able to open the 2nd most recently updated file for reading and close it etc.
Is there a built in method that allows a FileSystemObject
to sort the files or do we absolutely have to write custom sorting routine?
If we have to go with a custom sorting routine, is it possible to write this without having multiple functions? i.e. all code in the a main function.
Speed is a concern since there are to be a lot of files to sort through. Therefore any custom procedures should be efficient.
You could read the file names and dates into a disconnected recordset and sort that by date:
Set fso = CreateObject("Scripting.FileSystemObject")
Set list = CreateObject("ADOR.Recordset")
list.Fields.Append "name", 200, 255
list.Fields.Append "date", 7
list.Open
For Each f In fso.GetFolder("C:\some\where").Files
list.AddNew
list("name").Value = f.Path
list("date").Value = f.DateLastModified
list.Update
Next
list.MoveFirst
Do Until list.EOF
WScript.Echo list("date").Value & vbTab & list("name").Value
list.MoveNext
Loop
list.Sort = "date DESC"
list.MoveFirst
Do Until list.EOF
WScript.Echo list("date").Value & vbTab & list("name").Value
list.MoveNext
Loop
list.Close
