File Sync

Dropbox allows you to sync your files online and across your computers automatically.

• Work on files in your Dropbox even if you're offline. Your changes sync once your computer has an Internet connection again.
• Dropbox transfers correctly resume where they left off if your connection drops.
• Efficient sync: only the pieces of a file that changed (not the whole file) are synced. This saves you time.
• Doesn't hog your internet connection. You can manually set bandwidth limits.

File Sharing

Sharing files is simple and done in only a few clicks.

• See other people's changes instantly.
• A Public folder that lets you link directly to files in your Dropbox.
• Control who is able to access shared folders. Kick people out and remove the shared folders from their computers.
• Automatically create shareable online photo galleries out of regular folders.

Online Backup

Dropbox backs up your files online without you having to think about it.

• Automatic backup of your files.
• Undelete files and folders.
• Restore previous versions of your files.
• 30 days of undo history. Upgrades available for unlimited undo.

 

Web Access

A copy of your files is stored on Dropbox's secure servers. This lets you access them from any computer or mobile device.

• Manipulate files as you would on your desktop. Add, edit, delete, rename, etc.
• A Recent Events feed that shows you a summary of activity in your Dropbox.

  Security & Privacy

  Dropbox takes the security and privacy of your files very seriously.
  

  • Shared folders are viewable only by people you invite.
