What is a file system file header?

A file system file header is a data structure located at the beginning of a file that contains important information about the file. It typically includes metadata such as the file's name, size, creation date, modification date, and permissions. The file header also stores information about the file's location within the file system, such as the starting address and the number of blocks allocated to the file. Additionally, the file header may contain other attributes or pointers that are necessary for the file system to manage and access the file efficiently.
