AutoCleanFolder can scan your folders regularly to find and remove long unused files, saving you valuable disk space. You can customize the clean-up rules and implement regular batch clean-ups, such as setting a 30-day validity period for image files in Downloads and a 60-day period for other files. Expired documents will be cleaned up after your review, and the clean-up function will automatically run every day, which is equivalent to having an automatic clean-up machine on your hard drive.
