I have created a maintenance plan with only 1 task -- a cleanup task to delete all .bak files in the backup folder older than 1 week. The job completes successfully and the log file entry says it ran successfully but it's not deleting the old files. I have verified I have the file extension (.bak) and the backup folder correct. There are .bak files in that folder much older than 1 week but they do not get deleted. I checked the box that indicates to go 1 sub-folder below the one specified. At my last job I setup the maint plan this way and it worked fine.
