There are various kinds of file systems, which are as follows:
1. Disk file systems
On the disk storage medium, a disk file system has the ability to randomly address data within a few amounts of time. Also, it includes the anticipation that led to the speed of accessing data. Without regard to the sequential location of the data, multiple users can access several data on the disk with the help of a disk file system.
2. Flash file systems
A flash file system is responsible for restrictions, performance, and special abilities of flash memory. It is superior to utilize a file system that is designed for a flash device; however, a disk file system is the basic storage media, which can use a flash memory device.
3. Tape file systems
A tape file system is used to hold files on the tape as it is a tape format and file system. As compared to disks, magnetic tapes are more powerful to access data for a long time, which are the challenges for a general-purpose file system in terms of creation and efficient management.
4. Database file systems
A database-based file system is another method for file management. Files are recognized by their characteristics (like a type of file, author, topic, etc.) rather than hierarchical structured management.
5. Transactional file systems
Some programs require one or more changes to fail for any reason or need several file systems changes but do not make any changes. For instance, a program may write configuration files or libraries mand executables at the time of installing or updating the software. The software may be unusable or broken if the software is stopped while updating or installing. Also, the entire system may leave in an unusable state if the process of installing or updating the software is incomplete.
6. Network file systems
A network file system offers access to files on a server. In remote network-connected computers, with the help of local interfaces, programs are able to transparently create, manage and access hierarchical files and directories. The file-system-like clients for FTP and WebDAV, and AFS, SMB protocols, NFS are all examples of the network file systems.
7. Shared disk file systems
A shared-disk file system allows the same external disk subsystem to be accessed by multiple machines, but when the number of machines accesses the same external disk subsystem, there may be occurred collisions in this condition; so, to prevent the collision, the file system decides which subsystem to be accessed.
8. Minimal file system
In the 1970s, for some initial microcomputer users, disk and digital tape devices were much expensive. A few cheaper basic data storage systems used common audio cassette tape was designed. On the cassette recorder, the user was informed about pressing “RECORD” when there was required to write data by system. And, to notify the system, press “RETURN” on the keyboard. Also, on the cassette recorder, the user was needed to press the “PLAY” button when the system required to read data.
9. Flat file systems
The subdirectories are not available in the flat system. It contains the only directory, and all files are held in a single directory. Due to the relatively small amount of data space available, this type of file system was adequate when floppy disk media was available for the first time.
