Sparse files in Linux are a type of file that takes up less disk space than a regular file. They are files that contain large blocks of zero bytes, and these blocks are not actually written to disk. Instead, the file system records the location and size of these blocks, and the zero bytes are filled in as needed when the file is read. This allows sparse files to take up much less disk space than a regular file that is the same size. Why Use Sparse Files? There are several reasons why you might want to use sparse files…
