The software to store deleted files uses the Recycle folder, which is usually set up by the Windows operating system. This folder gives the computer one last chance to undelete a file or folder that the user may not have wanted to delete in the first place. This folder is dynamic and can be manipulated by the user. When the folder is full, the operating system may prompt the user to empty it. The operating system may also continue to write over older deleted files and folders as the recycle folder fills up.
