Disk Drive Structure

• The text explains how a computer's operating system organizes and represents information on a disk drive, using the analogy of a library.

Disk Drive Structure

• A disk drive is compared to a library, where files are like books and folders are like shelves.
• Folders can contain both files and other folders, creating a hierarchical structure.
• Files have a name and an extension, separated by a period.
• The extension indicates the file type (e.g., .docx, .xlsx, .pptx) or system files (e.g., .dll, .drv, .sys).
• The file extension was originally the main method of file identification in MS-DOS.
• Windows uses icons to visually represent different file types, such as a blue W for Word documents or gears for system files.
• Windows Explorer is a tool to view the contents of a computer.
• The structure is hierarchical, allowing navigation between drives, folders, and subfolders.
• It is possible to display or hide subfolders by clicking the cursors next to folder names.

File and Folder Properties

• File system organizes data in a hierarchical structure, beginning with the root directory.
• Each folder has the capacity to house more folders, which in turn can contain files and addtional folders.
• To view file or folder properties (name, size, location), right-click and select "Properties".
• The "General" tab shows key information.
• The content of a folder can be displayed in different ways (large icons, small icons, details, etc.).
• The "View" tab allows selecting display options.
• Icon view is useful for folders with images or music, showing a preview of the content.
• Detail view shows additional file information like date of creation and size.

File Recognition

• Recognizing common file types (text, spreadsheet, image, audio, video) is helpful.
• File extensions help identify the program associated with a file.
• Windows hides file extensions by default.
• It is possible to enable viewing file extensions in the Folder Options.
• Multimedia files have specific icons and extensions (.bmp, .jpg, .gif, .tif for images; .wav, .mp3 for music; .avi, .mpg, .mp4 for video).
• Executable files have extensions like .exe, .bat, or .com.

Opening Files

• Double-clicking a file, folder, or drive opens it.
• A double-click launches the associated application.
• Alternatively, right-click and select "Open" (or a single tap on touchscreen devices).

Naming Conventions

• Use meaningful names for files and folders for easy identification.
• Names should be descriptive and not too generic.
• Avoid overly long names, even though Windows supports up to 256 characters.
• The operating system allow special characters, with the exception of these /? : ; " < > * |

Folder management

• Right-click in a folder, select "New," then "Folder" to create a new folder.
• Name will be "New folder", but it is editable immediately, select rename and type a new name
• New subfolders can be created within new folder
• The creation of this folder system can be cascaded but not recommended if excessive because the location of files can be lost.
• Folders can be renamed slower double click on the existing name but make sure 1 second has passed to ensure the file opens
• A cursor will appear and allow editing
• A name can also be edited by selected the file via right click, and press rename

Organizing Files

• In File Explorer, typing directly will display a search and bring back the files.
• Select the properties name, date etc. to modify the search to more appropriate files.
• It can be extended to Documents, web, or another specific file such as Images, Music, People etc.
• It is possible to include partial words as files, and the system will show a list of names containing similar phrases.
• An asterisk can indicate all files with that extension such as *txt

File Organization

• Recent files in the app can be opened by right-clicking it from the taskbar.
• File structure is a basic storage foundation which works down a tree.
• To organize files use the right click.

Selecting Files

• Files can be selected by clicking, and pressing SHIFT on the keyboard while selecting files.

File Operations

• Commands can be given in several ways, pulldown menu, via icon, right-click or keyboard shortcut
• Selecting a file requires users to first select the file, and then go to Home and copy.
• To move a file, use the same procedure but select cut>paste instead of copy>paste.
• Cut option can be accessed by right clicking a folder, and selecting "Cut" and then pasting.

Deleting and Recovering Files

• Pressing the delete key or dragging to the recycle bin will "delete" a file.
• The same thing can happen by right-clicking a files and selecting delete.
• Recovering is possible by going to the desktop, and pressing Open Cestino
• It is then possible to restore the file, which the app will put the object back where it was
• Selected elements only can also be retrieved Selecting the clear recycle bin will delete the files forever.

Memory Support

• Memory support has several types, internal hard drive, CDR, Blu-ray etc
• Mass memory devices store data like applications, documents, files etc.
• The data stored is always relative to quickness, price, and capacity for storing.
• Byte and Kilobyte is a good measurement for such things

Units of Measure

• Hard drives contain all sorts of information
• USB are very tiny but powerful memory storage devices.
• Data stored by memory can be in several forms
• Memory has reduced in the way that the new SD digital device shows the same with less size
• RW CD and DVD all write, erase, and rewrite date.
• Disks are plastic that are read using microscopes
• Some sites offer the opportunity to save space and time.
• A local network is often used for sharing memory

Data Calculation

• Numbers are counted using decimal, but computers originally counted using 2 numbers
• Bit counts 0 or 1, and stores a character
• Kilobyte corresponds to 1000, megabyte corresponds to 1000 kilobytes, Gigabyte corresponds to 1000 megabytes.
• The measurement tools such as a byte are indicated by the ability to store memory, files etc.

Memory

• If memory is used it's capacity diminishes.
• The only way to see available space is to connect to a computer, and select properties via right-click.

File Compression

• Larger files now require a transfer, in order for computers to read/recognize one
• Compression allows a user to transfer a smaller, zipped version of a file for transportation and speed.
• Windows has now a compression program installed to create ZIP drives
• Files can be compressed when attaching file by zipping the file before sending

Compressions steps

• Clicking a folder or file via right click, then select Invia A and then a option to compress
• It will then display with a zip name and then name
• Or right-click and send ZIP
• Click with the right mouse button to send a file to a selected file
