File System – Organize Your Data Successfully!

February 4th, 2012 No comments

File system is a procedure of storing and organizing files in computer. Most importantly, it organizes files into a database for the storage, manipulation and retrieval by the computers operating system. File systems are used on hard disks or CD-ROMs to maintain the physical location of the files. Except this file systems provide access to data on a file server by acting as client for network protocol. The file system is accountable for organizing sectors into files and directories and keeps the record of which sectors belong to which file. It is can be used to represent and organize any data, whether it is stored or generated. File system usually used to secure storage location in the system memory. It has directories which associate file names with files. Now you can search more information about File system through the internet. You can also get several benefits by using file systems on your operating system.

As well referred to as the file system or else filesystem. System that the operating system and program makes use of organize & keep the track of files. Example, the hierarchical filesystem is one, which uses the directories for organizing the files in the tree structure. Though operating system gives own file management system, you may buy the separate file management. The systems also interact smoothly with operating system however give more and more features, like improved backup treatments & stricter file protection. Also, in computer, file system (at times written filesystem) is a way where files are been named & where they are been placed logically for the storage & retrieval. DOS, Windows, Macintosh, OS/2, as well as UNIX based systems have the file systems where files are been placed somewhere in the hierarchical structure. The file is been placed in the directory (the folder in the Windows) and subdirectory.

File System – Allowing the System for Unlimited Accessibility!

February 3rd, 2012 No comments

File system is much essential part of any computer or operating system because it’s set all the program or application in proper manners. So, it is much easier for the users to design the correct file system for their computer for secure their data. In this regard, you have required following process to do so! Basically, file system is categorizing and storing all sorts of files in the separate database, so the user can easily access any file in quick time without any search. At the same way, it is also separate the web files, system files, application files in different data base for easy accessibility. File system is also responsible to downloading or installing any application files in your computer. However, file system is also permits the system for unlimited accessibility from the several storage devices at a same time as well as stores many attributes of file in it.

The file systems specify the conventions to name the files and these conventions also include maximum number of the characters in name that characters are used, and, in a few systems, how long this file name suffix is. The file system as well includes the format to specify path to the file through structure of the directories. At times term generally refers to part of the operating system and added on program, which supports the file system like defined. Thus, there will be 65535 clusters to every FAT 16 disk. What it means, is as the hard drive gets very huge, the cluster count stays same, thus the cluster size increases. However, do not think for one minute you may indefinitely increase size of every cluster. This will not happen and reason is each and every sector inside the group needs to get numbered. Every sector has index number, which is written inside the byte. Byte is eight bits and what it means is number needs to be very less than 2^8. And as way you decrement in the computers is going by the powers of two, it means you may store number 2^7, or else 128 sectors.

File System – Access More Information!

February 3rd, 2012 No comments

Due to huge researches in technology filed, the researchers have been stated that file system is an important part of assortment operating systems. For more information, the file system is the best way to search the required files through any database. The procedure of file system is so simple to understand and users can locate their required files and documents easily. This sort of system is having numbers of benefits, so that it is the best option for those users who are facing problems for searching their required files in database. Also, this sort of system is keeping the file in tree structure through directory and subdirectory folders. Now, there are numbers of leading software companies available through which you can get your best solution to store your files and documents easily on your computer database. It’s the right time to get more information about this sort of system from the previous users.

The examples of add on file systems also include Network File System as well as Andrew file system. In specialized lingo of the storage professionals, file system is hardware that is used for the nonvolatile storage , software application, which controls hardware, as well as architecture of hardware & software. You can never figure out what they all meant. And this article can change that and by time I am done, you may know example what all these terms mean.

What is the File System?

First, let us now understand what the file system is. The file system is thought of as a way the computer goes about to manage files, which gets stored on the hard drive. The computer has plenty of files and in case, there were not any organized method to manage managing them, the system will be get slow, given it works. Take this mess, and multiply by thousand.

File System – Foundation of Any System Setting!

February 2nd, 2012 No comments

File system is also known as the foundation to stand any sorts of business because it does manage all the system in proper manner. It is one of the vital parts of any operating system because it manages all the files in the system data base. However, these sorts of advantage never available in case of previous system setting but now every system have file system for proper storage. If you are requires creating your ideal filing systems, then you have required some easy steps to follow such as: firstly you will choose the right option from plastic filing crate and keen filing cabinet. However, it is always important for the user to choose double space according to their requirement to avoid the further problem. Now, due to development of advanced technology, creating file system is become much easier. In this regard, file system of Microsoft Windows are becoming much popular than other.

There are some other file systems, which go beyond meeting the basic requirements by giving the additional functionality, like encryption, compression, password or permissions, filestreams, and so on. Later on in the article, I may discuss a few of extra features that are in relation to the Windows NT’s NTFS. This is also understandable in case, you consider how much of stuff that you have already piled in the office, how much time that is wasted to find stuff, which is buried under lots of paper.

FAT In Detail

The section is technical in the nature than rest of article. Feel totally free to skip in case, you want. However, get warned you can miss a few some interesting tidbits regarding FAT you never knew. Thus, what is FAT, how do the file systems actually work? Answer is very simple actually. Space on the hard drive, at the most basic level, is been divided in the units named sectors. Every sector is around 512 bytes.

File Systems – Essential Part of Operating System!

February 2nd, 2012 No comments

File systems are the vital part of operating system which has the capacity for long term storage. The mechanism for storing files and the directory structure are the two distinct part of file system. Now in the modern operating system it is possible for users to access same files simultaneously. File systems are also very necessary to control different forms of file in the operating system. It allows the system to access many different storage devices in the same way. The file system also stores a number of attributes for the files within it. All files have a name by which the user access it and most of the modern file system consist of three parts such as unique name, a period and extension. The file extension option enables the operating system to make a decision what to do with the file if somebody trying to open it.

It means every group will be made for handling one item and to illustrate point, think of following situation: File system chooses to divide people in groups of eight (we will get in how the number of selected later). All these eight people has the bag that will store stuff. File system hands first group the huge box of the pencils & says “store this.” Eight people begin to put pencils in the bags, and one fills up, and they move onto next and box of the pencils fills seven bags. File system tries handing group other small thing for putting in last 8th bag that is empty. However, group says “sorry, and we can just handle a thing. You already gave us one and file system says “ok, however you are wasting your space (1/8 = 0.125)” Group tells file system “sorry, we will not help it.” File system then moves on.

File System – Required Proper Process!

February 1st, 2012 No comments

The file system of any computer’s may corrupt or damage due to several reasons such as: power failures, incorrect shorting down process of the computer or any sorts of hardware failures. If your file systems become damage in Ubuntu Linux, then the “fsck” is the right option for you to correct the damage. The improper installation of Ubuntu will make an only panel for root directory. While there is a single file system then it is always better for you to use the Ubuntu installation CD to boot the system that files system being never used. In this regard, you are requires some particular process such as: disclose the terminal window that available under the Accessories option of the main application window of your computer system. In this way, type the “mount” command to locate the file system on your computer system. After that Insert the Ubuntu setting up CD in your CD and DVD drive to solve the problem.

Now file system gives next group of eight, just single pencil for storing. Group stores that & refuses to take something and file system informs group they are wasting 100% of the storage space and there is not anything they will do. The stories might appear silly, however they do get point across that is as size of clusters increase, amount of the space that you waste can increase. It is also true that in case, you will make your files precisely same size as the cluster, you will have 0% of waste. However, this is not at all possible. Typical files are not big, as well as if cluster size gets very huge, then waste is quite alarming. Thus, now question gets how does my PC figure out size of every cluster? Answer is very simple, take size of the hard drive, as well as divide it by number of the clusters involved.

File System – Allowing the Users to Access the Data Effectively!

January 31st, 2012 No comments

How to use the file system technology on a computer? This sort of question is playing an important role in every computer user’s life. If you are facing this sort of question, then you need to understand the file system procedure first. The file system is one of the best methods or techniques for storing and organizing the computer files and essential data.

Keep in mind that, this sort of storing procedure can be happened by a secure data storage devices which is easily manipulations, organize, and convertible. This sort of file system procedure has distinguished in two processes such as directory service and and registry. Also, the file system is responsible for addressing the data in fixed-sized units which is commonly known as Clusters, or Blocks. One of the most advantageous features of file system is allowing the users to access any sorts of data effectively through a computer.  Thus, what I am saying is:

Cluster Size = Disk Space or Number of the Clusters Possible

And as Cluster Size is straight proportional to the wasted space (and in other words, like cluster size increases, waste space as well increases), we may see what we want is the file system that will handle large number of the clusters. This is where the FAT16 and the FAT32 differ. The FAT32 will handle more groups then the FAT16 can. However, why is this? Simple explanation is FAT32 will count much higher than the FAT16. Like I said above, every cluster is been numbered by file system. The FAT16 makes use of 16 bit numbers for counting clusters. This means FAT16 makes use of binary numbers of around 16 digits. Consequence is that highest FAT16 will count to 2^16 – 1 or 65535.

Top 20 Linux Filesystem Tools

January 14th, 2010 4 comments

The Linux filesystem is complex and the first thing that most new users shifting from Windows will find confusing is navigating the Linux filesystem.

The second thing is that not too many people are familiar with how the filesystem works or know how to troubleshoot if any problems arise.

The good thing is, there are many different types of file system tools and utilities available to make troubleshooting easier but again not too many people are familiar with them. We’ve put together top 20 of the most useful file systems tools and utilities that you’ll find useful in your Linux environment.

  1. XFS – a high-performance journaling file system. It provides quick recovery after a crash, fast transactions, high scalability, and excellent bandwidth.
  2. e2salvage – a utility which tries to recover a data from damaged ext2 filesystems. Unlike e2fsck, it does not look for the data at particular places and it don’t tend to believe the data it finds; thus it can handle much more damaged filesystem. Moreover, fsck connects the found i-nodes to lost+found directory. e2salvage instead tries to recover the directory structure.
  3. e2fsprogs – contains essential ext2 filesystem tilities which consists of e2fsck, mke2fs, debugfs, dumpe2fs, tune2fs, and most of the ther core ext2 filesystem utilities.
  4. GNU Parted – a package for creating, destroying, resizing, checking, and copying partitions and the file systems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data between hard disks, and disk imaging.
  5. Partition Image – a Linux/UNIX utility similar to Symantec’s Ghost. This uility saves partitions in the EXT2, Reiserfs, NTFS, HPFS, FAT16, and FAT32 file system formats to an image file. The image file can be compressed with gzip or bzip2 in order to save disk space, and it can be split in order to fit onto a series of floppy disks. This program can be useful for backup purposes. A boot/root disk is also provided, allowing you to run Partition Image without Linux installed on the hard disk.
  6. reiserfs – revolutionary new approach to file system design which stores not just filenames but the files themselves in a B*-tree. It is a generation ahead of alternatives which use older plain B-tree technology, and cannot store the files themselves in the tree. Reiserfs doesn’t suffer from log congestion either, you can effectively use it for quickly creating a 100,000 entry directory, and it is fairly unique in that.
  7. Filesystem in Userspace – a simple interface for userspace programs to export a virtual filesystem to the Linux kernel. It also aims to provide a secure method for non privileged users to create and mount their own filesystem implementations.
  8. LUFS Userland Filesystem – a hybrid userspace filesystem framework supporting many “exotic” filesystems (localfs, sshfs, ftpfs, httpfs, socketfs, freenetfs, and nutellafs) transparently for any application. It can be regarded as doing the same job as the VFS (virtual filesystem switch) in the kernel: it is a switch, distributing the filesystem calls to its supported filesystems.
  9. EncFS – an encrypted pass-through filesystem which runs in userspace on Linux (using the FUSE kernel module). Similar in design to CFS and other pass-through filesystems, all data is encrypted and stored in the underlying filesystem. Unlike loopback filesystems, there is no predetermined or pre-allocated filesystem size.
  10. OpenAFS – a distributed filesystem which offers a client-server architecture, transparent data migration abilities, scalability, a single namespace, and integrated ancillary subsystems.
  11. IOzone – filesystem benchmark tool. The benchmark generates and measures a variety of file operations. Iozone has been ported to many machines and runs under many operating systems.
  12. FSlint – a toolkit to find various forms of lint on a filesystem. At the moment it reports duplicate files, bad symbolic links, troublesome file names, empty directories, non stripped executables, temporary files, duplicate/conflicting (binary) names, and unused ext2 directory blocks.
  13. SSH Filesystem – SSH Filesystem uses the SSH File Transfer Protocol (SFTP), which is supported by most SSH servers. It is based on Filesystem in Userspace (FUSE), and hence root privilege is not required for mounting a remote filesystem. No setup is necessary and it is very easy to use.
  14. Dump/Restore – The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
  15. Squashfs – a highly compressed read-only filesystem for Linux 2.4 and Linux 2.6. It uses zlib to compress files, inodes, and directories. All blocks are packed to minimise the data overhead, and block sizes of between 4K and 32K are supported. It is intended to be used as a filesystem for archival use and in embedded systems where low overhead is needed, and has been tested on PowerPC, i586, SPARC, and ARM architectures.
  16. Filelight – Filelight graphically represents a file system as a set of concentric segmented rings (or nested piecharts), aiming to show where disk space is being used.
  17. e2undel – an interactive console tool that recovers the data of deleted files on an ext2 file system under Linux. A library that allows you to recover deleted files by name is included. e2undel does not manipulate any internal ext2 structures, and it does not require any additional tools.
  18. SFS – a secure, global network file system with completely decentralized control. SFS lets you access your files from anywhere and share them with anyone, anywhere. Anyone can set up an SFS server, and any user can access any server from any client.
  19. Injector Linux – a single-floppy Linux system, which supports many filesystems — currently approximately 25. Because of its wide range of supported filesystems, it is very useful for disk rescue operations.
  20. File system investigator – a forensic tool for viewing filesystems. It is written entirely in Java, so it is platform independent. It allows viewing of ReiserFS and EXT2/3. While primarily intended as a forensics tool, it is also useful for Linux users who dual boot with another OS; it allows them to view and extract files from their partitions.

In conclusion, you don’t have to limit yourself to default tools available. Experiment with the applications mentioned above, stay ahead of the game by understanding how Linux filesystem is structured and utilized by users and applications.
