I have received messages from DropBox saying I am out of storage space so have logged into my account and sure enough shows I am out of storage space. I would like to know what has used up all the storage space because all I have stored is old photos. The last time I checked my Dropbox account there was plenty of space. Nothing I know about should have been added to the account. Has anyone come across this before? Or is it a ploy from DropBox to get me to upgrade the account? Could anyone point me in the right direction to finding out what is filling up the storage space?
