I accidentally tried to backup a large file and filled up all my available space on Dropbox. I searched the FAQs and ended up downloading the Desktop App which was supposed to allow me to delete the backup. It let me stop the backup, but did not free up the space taken up on Dropbox by the unintended backup. I keep getting the message that all my available space is used up and I need to upgrade. I can see that over 95% of my space on Dropbox is used by that backup. How do I reclaim the space used by the Backup? I've been searching and reading and have found nothing to help. I'd appreciate helpful directions.
