LLFW is a tool for Linux users that performs low-level format operations on disks. Thanks to its user-friendly interface and powerful features, you can easily perform operations such as filling with zeros, writing random data or secure erase.
System Maid, as its name suggests, is a system cleaner mini-suite developed for Debian-based Linux systems. The program performs tasks such as cleaning trash, history, and thumbnails, even using the overwrite method if the user prefers. It also supports performance tweaks such as disk defragmentation, limiting processor usage, and cleaning RAM.
