You can customize how Dropbox behaves (such as startup settings or bandwidth usage) by accessing the menu:
Third-party websites offering "cracked" or "older" Dropbox installers are common vectors for malware. Always verify the digital signature of DropboxInstaller.exe / Dropbox.dmg .
The magic is that this folder acts like any other folder on your computer—you can drag, drop, and save files directly into it—but the app works in the background to instantly sync those files to the cloud and any other linked devices.
: If a Windows security prompt appears, click "Yes" or "Run" to allow the installation.
