After installing the desktop application on Windows, the Dropbox folder will be located inside the folder with your user name (such as C:\Users\Panda\Dropbox). It may also appear in your Favorites list in Windows Explorer. Another easy way to open the folder is to click on the Dropbox icon in your system tray and then click Dropbox Folder in the pop-up panel.

Move your files into your Dropbox simply by dragging and dropping them into your Dropbox folder on your desktop. That's it. The files in your Dropbox folder will automatically be synced online and to your other devices. When working on a file, you can use the Save As... menu option in most applications to save files directly to your Dropbox folder. You can also upload files through the Dropbox website.

The window will disappear, you files will start uploading, and you’ll see a progress indicator. That’s it, you’ve added files to your Dropbox!
Note: Each file you upload through the website must be 10GB or less. For even larger files, use the desktop application or mobile app, which don’t have this limit.
Wanna see something awesome? If you use Chrome, Firefox, or Safari, you can upload files by dragging them from your desktop onto the Dropbox website.

If you’re working Dropbox on your desktop, you can create new folders the way that you normally would on your computer. You can also create a new folder to organize files on the web by hitting the “new folder” button in your top menu bar.
