Files and directories

A file refers to data stored on a hard drive or other storage media equally a separate entity. For example, you would normally save a thesis or a slide presentation or a photograph as a file. Files typically take the following characteristics:

A file always has a name.
A file ever takes up storage space.
A file is always saved in a certain format: a body of text is saved in one of the many text file formats, a photo in one of the many image file formats, etc.
A file contains information on when it was created and when it was concluding modified.
Files usually have access rights, especially if they are online.

Files are saved on the user'south own reckoner or in a remote location.

A directory or folder is a place where files or other directories are saved.

Name

Think carefully well-nigh how you name your files. Utilise descriptive file names then that even years later on y'all volition be able to recognize the contents of the file past its name. Avoid abbreviations and, instead, use whole words. For example, a file proper noun like "Cultural encounters" is amend than "Cult".

The naming conventions for files and directories vary by operating organisation: in Windows, for case, the dot in the file proper noun is usually followed by a file extension consisting of one or several characters that point the file type. In Linux, on the other hand, no extension is necessary.

Depending on the system, information technology may not be possible to utilise certain special characters (: > / * ? " > |) in the file proper noun. In add-on, using a infinite or Scandinavian umlauts (å, ä, ö) may sometimes cause problems, particularly over the Cyberspace. If you lot have problem posting files online, attempt removing special characters from the name.

In Linux, the use of UPPER Case and lower case letters in file names makes a departure; e.1000. Ray.txt is different from ray.txt. In Windows, upper and lower instance messages tin can be used more freely.

Paths

A string of text that shows the location of a file or directory is called a Path. The path to a single file on the hard drive of your home computer (in Windows) tin can be e.g.:

C:\Users\rkeskiva\Studies\Written report diary.docx

The path shows that a file chosen Report diary.docx is located on drive C in a subdirectory chosen Studies and stuff that belongs to user "rkeskiva". The same information can exist presented graphically:

File types

A file can contain different kinds of material: text, video so forth. When the contents of a file are saved in a certain generally known format, it is called a file type. Photographs, for example, are oft stored as JPEG image files, and discussion processing documents as DOCX or RTF document files.

In Windows, the file blazon is axiomatic from the file extension (normally consisting of three letters) that follows the dot in the file name. The file extension indicates the format in which the data in the file has been stored.

Please be careful when dealing with file extensions in operating systems, including Windows: if you change an extension or leave it out, the operating organisation might not know which application to use to open up the file! Opening the file through the right application will also be more difficult because the file will non exist displayed in the default view of the Open menu window within the application.

If the directories in Windows do non bear witness the file extension (meet the icon below on the left), it is hard to make up one's mind the file type.

To view file extensions, open the Control Panel and click on Appearance and Personalization. Then, click File Explorer Options. In the window that opens, go to the View tab and ringlet down the Advanced settings list. Untick the box for Hibernate extensions for known file types and accept the change by clicking OK. File extensions will now be displayed (encounter the picture on the right).

File size and units of measurement

Agreement file sizes is very useful. Too big a file sent as e-mail may completely fill the recipient's mailbox or information technology may cause your message not to leave at all. Similarly, you may not be able to salve several large files on a USB flash drive if y'all don't know how to estimate the total amount of space they need.

Data is saved in binary grade, i.eastward. as numbers consisting of ones and zeros. The smallest data storage unit – the chip (b) – can receive the value one or 0. When several bits are combined in a row, they form a byte (B). A byte may look like this, for example: "01011001". If you type the word "data" on your computer, it consists of four bytes (each letter of the alphabet usually consists of i byte).

The storage chapters is specified equally the maximum number of bytes that the storage media can hold. The storage capacity is often and then large that it is described as follows:

Unit	Abbreviation	Size in bits or bytes
byte	B (Byte)	1 byte = 1 character = 8-bit cord
kilobyte	kB	1024 bytes
megabyte	MB	1024 kilobytes
gigabyte	GB	1024 megabytes
terabyte	TB	1024 gigabytes

The size of a file depends very much on the file blazon. A document of i page that just contains text may be equally small-scale equally 3 kB, while a photo may be three MB or much larger (the image size depends on the format the epitome is saved in). A whole movie can easily have several gigabytes of storage space.

Creation and modification dates

When the file window is fix to display all of the details of the files, you will frequently see the Appointment Modified for each file.

If y'all want to check when the file was originally created (Date Created), right-click the file and select Properties from the carte that opens. The creation and modification dates are and then shown equally follows:

Managing file and folder views

You tin change the binder view in club to come across the file and folder details in your preferred format (e.yard. as thumbnails or with the dates visible). In Windows 10, you can alter the view by clicking the buttons at the bottom right of the window (see the image below).

The same options can exist accessed via the View menu, which can exist displayed by pressing the Alt key on the keyboard.

You can sort files and folders past clicking the headings higher up the list. For example, to sort files by their date of modification, click the Engagement Modified heading (run into the prototype higher up). Yous tin can reverse the order of the files by clicking the heading again.
