Study Notes

Computer Files

A computer file is a collection of data stored on storage devices like hard drives or SSDs.
Files can hold various content types: text, images, videos, software programs, and system data.
Each file has a unique name and is organized within a directory structure.
Files can be created, modified, and accessed by users and programs.

Computer Directories

A directory organizes files in a structured way, acting like a virtual container.
Directories can contain files and subdirectories, forming a hierarchical tree-like structure.
The path to a file starts from a root directory, mapping steps through subdirectories.

Drive Letters

Drive letters are alphabetic characters assigned to storage devices (e.g., C:, D:).
They simplify the identification and access of file locations across different drives.

Windows File Explorer

Windows File Explorer is the file management tool in Microsoft Windows.
It provides a graphical interface to browse, manage, and organize files and directories.
Users can view, move, copy, delete, rename files, and search for specific files or folders.

File Extensions

A file extension is a suffix indicating the file's format or type, typically 3-4 characters long (e.g., .txt, .jpg).
File extensions help the operating system recognize how to handle different file types.
Common file types include:
- .docx /.doc: Microsoft Word documents.
- .xlsx /.xls: Microsoft Excel spreadsheets.
- .pptx /.ppt: Microsoft PowerPoint presentations.
- .pdf: Portable Document Format.
- .jpg /.jpeg: Compressed image format for photographs.
- .png: Image format supporting transparency.
- .mp3: Audio format using lossy compression.
- .mp4: Video format known for good quality and compression.
- .zip: Compressed archive containing multiple files.
- .exe: Executable files for Windows programs.
- .html: Format for creating web content.
- .csv: Tabular data format using commas.
- .gif: Image format supporting static and animated graphics.
- .txt: Basic text file for unformatted content.

File Associations

File associations link file extensions to specific applications for opening and managing files.
Users can change default applications for specific file types in operating system settings.

File Attributes

Common file attributes include:
- Read-Only: File cannot be modified.
- Hidden: File not visible in standard listings.
- System: Essential for operating system operations.
- Archived: Marked for backup or archiving.
- Compressed: Saved space by compressing the file.
- Encrypted: Accessible only to authorized users.
- Read/Write: File can be modified.
- Indexed: Contents indexed for efficient searching.
- Temporary: Intended for short-term use.
- Offline: Stored in secondary or network locations.

File Dates

File dates provide timestamps for tracking actions:
- Creation Date: When the file was first created.
- Modification Date: Last time the file was changed.
- Access Date: Last time the file was opened.
- Metadata Change Date: When the file’s attributes were altered.
