Linux supports many file systems (for example: ext3, NTFS, FAT32, etc.).
The following diagram shows how Linux allows a process to access files:
So assume that a process called the
read() system call to read a file, what will happen is that the VFS layer will be accessed, and the VFS layer will decide which file system driver to access based on the file system of the partition that the file to be read resides on.
Linux provides many system calls to access files (for example:
rename() work on all the file systems that Linux supports.
But there are specific features that exist only on some file systems while not existing on others. For example: on a NTFS file system, you can set the Archive bit for a file, while this can't be done on an ext3 file system.
Now my question is, does Linux have system calls to access all the features of the file systems it supports? for example: does Linux have a system call to set the Archive bit for a file on a NTFS file system?
