Spring Cleaning 11 Deluxe is a utilities program developed by Smith Micro Software, Inc. for keeping the Mac operating system running in optimal condition. The program searches through the system to find corrupted or duplicates files, hidden application data created during installations, and unnecessary files, such as logs and shortcuts, that can be deleted to save drive space. As the software tracks down the junk in the system, an overview of the amount of space each file or folder occupies is provided to users. Meanwhile, users may schedule system scans and set the program to immediately delete junk files. In case of mistake, the software can undo its previous actions and restore deleted files to their former places. As a bonus feature, users can easily share their files through SendStuffNow, which is another service from Smith Micro that allows shared files of up to 2 gigabytes in a single download.
