Im looking for a way to do this in Excel 2010 using VBA.
It used to be possible in Excel 2003 using the Application.FileSearch method, but this has be depreciated. (
If using the FileSystemObject is acceptable, you could use the method described here.
To summarize:
Dim fso As Scripting.FileSystemObject
Dim fol As Scripting.Folder
Dim fdr As Scripting.Folder
Dim fil As Scripting.File
Dim flc As Scripting.Folders
Set fso = CreateObject("Scripting.FileSystemObject")
Set fol = fso.GetFolder("YourPathName")
Set flc = fol.SubFolders
For Each fdr In flc
For Each fil In fdr.Files
Debug.Print fil.DateLastModified
Next fil
Next fdr
Set fso = Nothing
Set fol = Nothing
Set flc = Nothing
