The main window of the TrashLater application.

This is where you define which folders should be watched. When you select a folder name, more details will be shown in the panel on the right.
Double-click a folder name to change its settings.

The Folder Inspector
The example shows the settings for the "Temporary" folder (see window title).
In the upper part, you can select what action is to be applied to items that meet the conditions in the list below. They can be moved to the Trash, deleted, or moved elsewhere. Optionally, files can be moved into dated subfolders - one new folder for each day.
You can add a number of conditions that items inside this folder must meet. In the example, there is only one condition, which specifies a grace period of 7 days.
More settings are available under the Options tab (not shown here).

The TrashLater Client in action.
Here
you can follow the progress of the folder checking procedure. (provided you
have enabled it in the preferences).

Growl Notifications
No progress window is shown when the background-only process is used to check the folders. However, TrashLater can make use of Growl to show selected status messages, for instance after a daily check was completed.
