Does your instance of SQL Server have xp_cmdshell enabled? If so you can capture the result of the DOS command "DIR" into a table variable containing the date and time. Here is a snippet of code that I use for looking for database backups using this method:

set @FullyQualifiedPath = @BackupPath + '\' + @Database_Name

set @DirectoryCmd = 'dir /b /o:-d ' + @FullyQualifiedPath + '\*.bak'

delete from @DatabaseBackups

insert into @DatabaseBackups (BackupFileName)

exec xp_cmdshell @DirectoryCmd

delete from @DatabaseBackups

where BackupFileName is null or

charindex(@TodayDate, BackupFileName) = 0

Here is the table definition for @DatabaseBackups:

declare @DatabaseBackups table (database_id int

,BackupFileName varchar(max))

This gives you an idea what you can do. You can capture the date/time of the files then process what ever you want.

Hope this helps.
