When have a lot of Dropbox activity, then your Dropbox cache can grow, especially when you have clashes of files in use on other machines, and manipulating them from another.
In fact, I managed to get the Dropbox cache to be about as big as the first post on this thread.
Here are the steps to clear your cache on a Windows system:
- Stop the Dropbox.exe (from the tray, right click you your Dropbox icon, then click exit)
- Verify (in the Task Manager – make sure you view all processes from all users – or in Process Explorer) that Dropbox.exe is not running any more
- Delete the dropbox cache directory (or move it to the Recycle Bin)
- Start Dropbox (from the Start menu, it normally is under the Dropbox group)
The location of your Dropbox cache is in: %APPDATA%\Dropbox\cache, the actual location depends on what Windows version you are:
- For Windows Vista and up (including Windows 7 and Windows 2008 Server), it is at C:\Users\Username\AppData\Roaming\Dropbox\cache.
- For older Windows versions (XP, 2003 Server, and older), the Dropbox cache is at C:\Documents and Settings\Username\Application Data\Dropbox\cahche.
