File and folder are commonly used important terms in computer terminology. Any kind of data on your hard drive consists of files and folders. Today we discus on File vs Folders. The main difference is that files are used to store data, while folders store files and other folders or directory on your computer.

Difference between File and Folder

The part of the operating system responsible for managing files and directories is called the file system. It organizes our data into files, which hold information, and directories also called "folders" , which hold files or other directories. Several commands are frequently used to create, inspect, rename, and delete files and directories.

To start exploring them, let's open a shell window:. The dollar sign is a prompt , which shows us that the shell is waiting for input; your shell may show something more elaborate. In these lessons, we're going to explore Nelle's files. You can optionally download the example files and directories which Nelle is using, so that you can explore the same files as described in the lesson. To do this, download the zipped filesystem by clicking this link. Unpack the zipped files - on Windows or a Mac, you can probably just double-click or click the downloaded file to unpack it.

On linux you can type in a command like. Once you have Nelle's files and directories, change to Nelle's home directory to begin, by typing in the cd command:. Type the command whoami , then press the Enter key sometimes marked Return to send the command to the shell. The command's output is the ID of the current user, i. Next, let's find out where we are by running a command called pwd which stands for "print working directory". At any moment, our current working directory is our current default directory, i.

If the command to find out who we are is whoami , the command to find out where we are ought to be called whereami , so why is it pwd instead? The usual answer is that in the early s, when Unix was first being developed, every keystroke counted: the devices of the day were slow, and backspacing on a teletype was so painful that cutting the number of keystrokes in order to cut the number of typing mistakes was actually a win for usability.

The reality is that commands were added to Unix one by one, without any master plan, by people who were immersed in its jargon. The result is as inconsistent as the roolz uv Inglish speling, but we're stuck with it now.

To understand what a "home directory" is, let's have a look at how the file system as a whole is organized. At the top is the root directory that holds everything else. Inside that directory are several other directories: bin which is where some built-in programs are stored , data for miscellaneous data files , users where users' personal directories are located , tmp for temporary files that don't need to be stored long-term , and so on:.

When it appears at the front of a file or directory name, it refers to the root directory. When it appears inside a name, it's just a separator.

Let's see what's in Nelle's home directory by running ls , which stands for "listing":. The names that don't have trailing slashes, like notes. And note that there is a space between ls and -F : without it, the shell thinks we're trying to run a command called ls-F , which doesn't exist.

You may have noticed that all of Nelle's files' names are "something dot something". This is just a convention: we can call a file mythesis or almost anything else we want. However, most people use two-part names most of the time to help them and their programs tell different kinds of files apart.

The second part of such a name is called the filename extension , and indicates what type of data the file holds:. This is just a convention, albeit an important one. Files contain bytes: it's up to us and our programs to interpret those bytes according to the rules for PDF documents, images, and so on. Naming a PNG image of a whale as whale. Now let's take a look at what's in Nelle's data directory by running ls -F data , i. The second argument—the one without a leading dash—tells ls that we want a listing of something other than our current working directory:.

The output shows us that there are four text files and two sub-sub-directories. Organizing things hierarchically in this way helps us keep track of our work: it's possible to put hundreds of files in our home directory, just as it's possible to pile hundreds of printed papers on our desk, but it's a self-defeating strategy. Notice, by the way that we spelled the directory name data. It doesn't have a trailing slash: that's added to directory names by ls when we use the -F flag to help us tell things apart.

And it doesn't begin with a slash because it's a relative path , i. According to Wikipedia , the terms argument and parameter mean slightly different things. In practice, however, most people use them interchangeably or inconsistently, so we will too. What if we want to change our current working directory? We can use cd followed by a directory name to change our working directory. Sure enough, if we run pwd after running cd.. The special directory.. If we want to display it, we can give ls the -a flag:.

As you can see, it also displays another special directory that's just called. It may seem redundant to have a name for it, but we'll see some uses for it soon. The special names. When the meanings of the parts are the same no matter how they're combined, programmers say they are orthogonal : Orthogonal systems tend to be easier for people to learn because there are fewer special cases and exceptions to keep track of.

Knowing just this much about files and directories, Nelle is ready to organize the files that the protein assay machine will create. First, she creates a directory called north-pacific-gyre to remind herself where the data came from.

Inside that, she creates a directory called , which is the date she started processing the samples. She used to use names like conference-paper and revised-results , but she found them hard to understand after a couple of years. The final straw was when she found herself creating a directory called revised-revised-results Nelle names her directories "year-month-day", with leading zeroes for months and days, because the shell displays file and directory names in alphabetical order.

If she used month names, December would come before July; if she didn't use leading zeroes, November '11' would come before July '7'. This is what she used in her collection log to record the location, time, depth, and other characteristics of the sample, so she decides to use it as part of each data file's name.

All files will go into the same directory. Pressing tab again does nothing, since there are possibilities; pressing tab twice brings up a list of all the files, and so on. This is called tab completion , and we will see it in many other tools as we go on. What does the command ls do when used with the -s and -h arguments? Fork me on GitHub. Files and Directories Objectives Explain the similarities and differences between a file and a directory. Translate an absolute path into a relative path and vice versa.

Construct absolute and relative paths that identify specific files and directories. Explain the steps in the shell's read-run-print cycle. Identify the actual command, flags, and filenames in a command-line call. Demonstrate the use of tab completion, and explain its advantages. Key Points The file system is responsible for managing information on the disk. Information is stored in files, which are stored in directories folders.

Directories can also store other directories, which forms a directory tree. A relative path specifies a location starting from the current location. An absolute path specifies a location from the root of the filesystem. Most files' names are something. The extension isn't required, and doesn't guarantee anything, but is normally used to indicate the type of data in the file.

Most commands take options flags which begin with a '-'. What does the command cd without a directory name do? It has no effect. It changes the working directory to the user's home directory. It produces an error message.

Computer Basics: What Is the Difference Between a File and a Folder?

The main difference between file and folder is that a file stores data while a folder stores files and folders. A file and folder are two terms used in computing. A file is a container to store information. There are different types of files such as text files, data files, images, audio files, and video files.

We used to come up with the terms file and folder on a very frequent base, and these are the common terms in the computer field. On the other hand, a folder is quite more than a container used to store files. It would not be practically possible to put several hundred or thousands of paper files on a desk, as when you need a particular file from those papers it is next to impossible find it. So, that is the reason we store paper files in folders inside a filing cabinet.

File and folder are commonly used terms in computer terminology. One comes across these terms a lot when using a Windows based system. Often people, mainly beginners are confused when using these terms. Basically all the data in a hard drive is contained in either files or folders.

The part of the operating system responsible for managing files and directories is called the file system. It organizes our data into files, which hold information, and directories also called "folders" , which hold files or other directories.

Paul's passion for technology and digital media goes back over 30 years. Born in the UK, he now lives in the US. Understanding the terminology is important when you are learning about computers. One thing that beginners can find difficult is understanding the difference between files and folders.

A file is an object on a computer that stores data , information , settings, or commands used with a computer program. In a GUI graphical user interface , such as Microsoft Windows , files display as icons that relate to the program that opens the file. If a program is associated with a program, double-clicking the icon opens it in the default program. A file is created using a computer software program. For example, to create a text file you would use a text editor , to create an image file you would use an image editor , and to create a document you would use a word processor.

The operating system organizes all the data in the hard drive as files and folders. It maintains a directory or folder structure to store data in a computer storage media like a hard disk or a CD. A file can be either a data file or a program file. A file is represented with the icons of the program they are made in, which makes it easy to recognize a type of file. The folders are often referred to as directories and are used to store files on the computer. Folders can also be used to store other folders which are usually called subfolders. Files are stored in various formats while folders store different files and subfolders on the hard drive.

Key Differences Between File and Folder

 Вовсе нет, - ответила Мидж.  - Хотела бы, но шифровалка недоступна взору Большого Брата. Ни звука, ни картинки. Приказ Стратмора. Все, что я могу, - это проверить статистику, посмотреть, чем загружен ТРАНСТЕКСТ. Слава Богу, разрешено хоть .

Нет сомнений, что человеческий мозг все же совершеннее самого быстродействующего компьютера в мире. В какую-то долю секунды сознание Беккера засекло очки в металлической оправе, обратилось к памяти в поисках аналога, нашло его и, подав сигнал тревоги, потребовало принять решение. Он отбросил бесполезный мотоцикл и пустился бежать со всех ног. К несчастью для Беккера, вместо неуклюжего такси Халохот обрел под ногами твердую почву. Спокойно подняв пистолет, он выстрелил.

 Ну ладно, - вздохнул Стратмор.  - Похоже, вышла какая-то путаница.  - Он положил руку на плечо Чатрукьяна и проводил его к двери.  - Тебе не нужно оставаться до конца смены. Мы с мисс Флетчер пробудем здесь весь день. Будем охранять нашу крепость. Желаю веселого уик-энда.

Техники обнимали друг друга, подбрасывая вверх длинные полосы распечаток. Бринкерхофф обнимал Мидж. Соши заливалась слезами. - Джабба, - спросил Фонтейн, - много они похитили.

Определить ключ стало столь же математически нереально, как найти нужную песчинку на пляже длиной в три мили. Было подсчитано, что для успешной атаки на стандартный ключ самому быстрому компьютеру АНБ - секретнейшему Крей-Джозефсону II - потребуется более девятнадцати лет. К тому времени когда компьютер разгадает пароль и взломает шифр, информация, содержащаяся в послании, утратит всякую ценность. Оказавшись в условиях подлинного разведывательного затемнения, АНБ выпустило секретную директиву, одобренную президентом Соединенных Штатов. Заручившись поддержкой федеральных фондов и получив карт-бланш на все необходимые меры для решения проблемы, АНБ приступило к созданию невозможного - первой универсальной машины для вскрытия шифров.
