Step-by-step explanation:
File system keeps track of files that are saved and where they're stored on the disk. It provides a logical framework for organizing and accessing files. Each file system has its own way of organizing data on a storage device such as a hard drive or SSD.
For example, in Windows, the File Allocation Table (FAT) and New Technology File System (NTFS) are commonly used file systems.
Defragmenting is a process to optimize storage on a disk by rearranging fragmented files, while disk cleanup helps to free up space by deleting unnecessary files. Formatting, on the other hand, erases all the data on a storage device and prepares it for use.
