Move to recycle bin – move the useless files to recycle bin. It is a safer choice in case some errors occur after cleanup. You can restore the deleted files.
Shred – overwrite files with random data and erase them to make sure the files are permanently gone. The is useful when you need to delete some stubborn files or need to protect your privacy and eliminate the possibility that someone might see or recover them.
