What is Physical and Logical Filesystem?

Physical files contain the actual data that is stored in the storage. (Ex: device's solid-state drive (SSD), hard-disk drive (HDD) or other media.)

Logical files do not contain data. They contain a description of records that are found in one or more physical files. Each logical drive is assigned its own drive letter and can be formatted with a file system to store data. Logical drives are created through a process called partitioning. Partitioning involves dividing a physical drive into multiple sections, each of which can be assigned as a separate logical drive. This can be done using various disk management tools or utilities provided by the operating system, such as Disk Management in Windows.
