From the developer:
A file removal utility that enforces a grace period before any move takes place. Items can be moved to other folders or to the Trash.
During its operation, TrashLater watches over selected folders, keeping track on their contents. Any unmodified file that resides in a folder for longer than the grace period is removed. Modified files are regarded as new files.
Beginning with version 4.2, TrashLater can be run as a system daemon.
