KleanSweep allows you to reclaim disk space by finding unneeded files. It can search for files basing on several criterias; you can seek for:

* empty files
* empty directories
* backup files
* broken symbolic links
* broken executables (executables with missing libraries)
* dead menu entries (.desktop files pointing to non-existing executables)
* duplicated files
* orphaned files
* obsolete thumbnails
