Know the core folders that make up the C:\Windows structure It's essential for any user who wants to master their operating system, perform maintenance tasks, free up space, or simply understand what's actually on their computer's hard drive. Beyond curiosity, this knowledge allows you to avoid fatal errors (such as deleting system files), make better use of your computer's hard drive, and even improve your performance. storage and, above all, know how to find, move or protect your personal files and favorite programs.
If you've ever wondered what all those folders on your C:\ drive are for, or how to locate the files that are taking up the most space on your PC, you've come to the right place. Below, we invite you to explore every corner of the Windows directory, from the default folders up to the commands and Tricks more advanced tools for organizing, searching, and managing files and directories on your Windows 10 or 11 computer.
Main structure of the C:\ drive and its most important folders
When you install Windows, the C:\ drive is organized around three fundamental directories:
- Windows: It's the heart of the operating system. It houses the essential files for Windows to function, from executables to critical libraries.
- Program Files (Program Files): The default location for installing most applications. On 64-bit computers, you'll also see "Program Files (x86)," which is intended for 32-bit programs.
- Users: Folder where information for all users on the computer is stored. Inside, you'll find subfolders for each user, such as C:\Users\John, C:\Users\Mary, etc.
Within each user folder, additional directories are generated such as Desktop, Documents, Downloads (Downloads), Pictures, Music and others, which serve as a personal archive for each account.
What are special folders in Windows and what are they used for?
Windows has a number of special folders Even if they change physical location (for example, if you move them to another drive to save space), the system and applications will continue to automatically recognize them thanks to unique identifiers (GUIDs). These folders are designed to facilitate access to documents, settings, and resources for both the user and the operating system itself.
- Documents: Main storage for personal files.
- Downloads: Where files downloaded from the Internet are stored.
- Images, Music, Videos: Intended for multimedia files organized by type.
- AppData: Folder where programs and the system itself store user-specific settings, caches, and temporary data.
- Public: Folder to share files between users of the same computer or via a local network.
These folders can be quickly opened using commands Shell ('Windows + R' and then type commands like shell: downloads o shell:documents), which makes it quicker to access your content without manually navigating through the file explorer.
Quick access and efficient organization in File Explorer
Starting with Windows 10 and especially Windows 11, the system offers Quick Access in File Explorer. Frequently used folders (Desktop, Documents, Downloads, etc.) are pinned here by default, making them easy to locate. You can pin any folder that you use often with a simple right-click and selecting “Pin to Quick Access.”
In newer versions of Windows, these default folders no longer appear in the "This PC" view, allowing the focus to be on network drives and locations. However, you can display libraries again in the left pane from the "View" tab by selecting "Show Libraries."
Many of the customizations, such as moving personal folders to another partition, require a basic procedure: First, create the new destination folder, then right-click the original folder, go to Properties > Location, and click "Move." This will replace your personal files' path with the new location, keeping them accessible from the system and avoiding space issues on the main partition.
Libraries, absolute and relative paths: key concepts
Windows Libraries These aren't actual folders, but rather indexes that group files from different locations under a single view. For example, your Documents library can display files stored in both Documents and Music if you configure it to do so.
On the other hand, understanding the difference between absolute path (which always starts from the root, C:\) and relative path (which starts from the current folder) is essential for moving around the system and executing commands in the console (DCM). Example:
- Absolute route: C:\Users\Juan\Documents
- Relative path: ..\..\Maria\Documents (from John's Desktop to Maria's Documents)
This knowledge prevents confusion and helps automate tasks such as backups or custom scripts.
Managing folders and files from the terminal: essential commands
El symbol of the system (CMD) and PowerShell allow you to manage files and folders in an advanced way with commands such as:
- CD : Change to the specified directory. Use Cd .. to go to the father and cd \ to return to the roots.
- DIR : Lists files and subdirectories. /s displays all the contents of the structure, /p pause per page.
- MKDIR or MD: Create a new directory.
- RMDIR or RD: Removes directories. Adds /s to erase with all its contents and /q to do so without confirmation.
- XCOPY /E source destination: Copies entire directories, including empty subfolders.
- COPY source destination: To copy files only.
- TIME : Delete files. /S also deletes those in subdirectories.
- REN newname: Renames files in the same folder.
- MOVE origin destination: Move or rename files.
- TYPE file.txt: Displays the contents of plain text files on the screen.
- ATTRIB: View and modify attributes such as read, hidden, or system on files and directories.
These commands are useful for automating advanced tasks, cleaning up files, organizing folders, or freeing up space without relying on the graphical environment.
How to find larger folders and files and free up space
One of the biggest headaches in Windows is the lack of spaceTo find out which folders are taking up the most space, there are several alternatives:
- Settings> StorageWindows provides an overview of the space used by folders and programs by going to Settings > System > Storage. Clicking on each section displays the distribution of that space.
- File Browser: You can check the size of each folder by right-clicking > Properties, although browsing through them all manually can be tedious.
- External tools: There are programs like "SpaceSniffer" or "EaseUS Partition Master" itself with space analysis utilities that graphically display the largest folders and files.
- Symbol of the system: You can use commands like FORFILES /S /C «cmd /c if @fsize GTR 1048576 echo @path.txt» To generate a list of files larger than 1 MB, or the command DiskUsage of Windows 10/11, which allows you to list folders by size (for example, “diskusage /t=5 /hc:\windows” returns the 5 largest folders in C:\Windows).
These methods are ideal for cleaning your system, detecting forgotten files, and keeping track of how much space is being used by games, movies, or old backups.
Attributes, hidden files, and access to critical folders
Windows marks certain files and folders special with attributes such as Hidden (H), Read only (R) or System (S). These files are not visible by default in the browser. To view them:
- Open "File Explorer".
- On the View tab, select Options and enable Show hidden files and folders.
To change these attributes from CMD, use the ATTRIB command. For example, attrib -H -S file.txt Removes hidden and system attributes, allowing you to edit or delete the file if necessary. Be careful: Removing attributes from system files or deleting them can render your computer unusable.
Usefulness of moving personal folders and practical recommendations
Recommended Move personal folders (Documents, Pictures, etc.) to another partition or disk to avoid filling up the system partition and facilitate its recovery before formatting. The correct process is:
- Create the destination folders where you want to move your personal files.
- Right-click the original folder (e.g., Documents), select Properties > Location > Move, and choose the new path.
- Let the wizard move all the content and check that you haven't mistakenly placed one folder inside another to avoid disasters.
It is not recommended to move personal folders directly to the root of C:\, as this can cause confusion and permission issues.
