The 260 character limit on the file path makes deleting the file from applications like Weblogic problematic (especially the .patch_storage sub-folder structure). As a result the PeopleTools DPK “cleanup” command doesn’t actually clean everything up.
Use:
ROBOCOPY D:\TEMP\EMPTY .patch_storage /PURGE |
or /MIR to delete the files recursively, where D:\TEMP\EMPTY is an empty folder.
