Files and folders in File Explorer
By the endYou have a practice folder named after the example app on your Desktop, and you can open, rename and move files.
Everything you keep on a PC is a file: a photo, a note, a picture of your app's screen. Files are kept in a folder, and a folder can hold other folders. The app that shows them is File Explorer.
Open File Explorer
Click the yellow folder icon on the taskbar. Or hold Windows and press E. A window opens.
Down the left side is the sidebar. The places you will use most:
- Desktop: what is on your screen behind the windows.
- Documents: a good home for long-term files.
- Downloads: where the browser puts files from the internet.
- Pictures: where screenshots go.
- This PC: everything on the computer, including how much space is free.
The main area shows what is inside the place you clicked. Folders are yellow. Files show a small picture of their contents or of the app that opens them. Double-click a folder to go into it. Click the < arrow at the top-left of the window to go back.
About OneDrive
Many PCs keep the Desktop, Documents and Pictures folders in OneDrive, Microsoft's online storage. You can tell because those folders show a small cloud or a green tick next to each file, and the sidebar lists them under a cloud icon named OneDrive. This is fine. Your files are still on the PC, and a copy is also kept online, which protects them if the PC breaks. The only thing to know: when a step says "Documents", it may be the Documents inside OneDrive on your PC. Both are the same folder.
Make the Binder folder
This folder is for practice. In Part 4 you will make the real one for your app.
- Click Desktop in the sidebar.
- Right-click an empty spot in the main area. A menu appears.
- Click New, then Folder. On Windows 11 you can instead click the New button at the top-left of the window, then Folder. A yellow folder appears, named "New folder", with the name highlighted.
- Type
Binder. The old name is replaced as you type. - Press Enter. The folder is now called Binder. It also appears on your Desktop.
Rename, move, delete
- Rename: click the folder once to select it, press F2, type the new name, press Enter. Or right-click it and click Rename (on Windows 11 it may be a small icon at the top of the menu).
- Move: drag a file onto a folder and let go. It goes inside.
- Delete: click a file once and press Delete. Or right-click it and click Delete (a bin icon on Windows 11). The file waits in the Recycle Bin on the Desktop until you empty it, so a mistake can be undone.
Practice
- Double-click the Binder folder. It opens, empty.
- Click the < arrow to go back to Desktop.
- Rename the folder to
Binder practice, then rename it back toBinder.
