Dropbox says not enough space, but there is plenty of space

So you have 30 MB left in Dropbox storage. You try to store a 20 MB file in the Dropbox folder in your (windows) explorer and get a message like: Can't sync examplefile.xxx...out of space in your Dropbox Oh no! What do you do? Two solutions that may solve your problem.

This may sound like a stupid question, but do you have enough space on your physical drive? Since Dropbox acts as a folder on your physical drive there has to be enough space on that drive as well for it to sync and for it to be stored in your Dropbox folder. 


Have you cleared the Dropbox cache? This is the path in Windows Explorer (assuming you're using Windows 7) %HOMEPATH%\Dropbox\.dropbox.cache type that line in the location bar in Windows Explorer and it should take you to the dropbox cache folder. I think the cache folder is deleted automatically every 3 days, but if you just recently deleted a lot of files this could be taking up valuable space in your dropbox folder.

I hope one of these helps.
