Hi Arthur Herron,
Adobe Acrobat.com offers 5 GB of free online storage but you cannot upload audio or video files including Adobe’s own Flash video format.
You may however store PDFs, Office documents, images, Adobe formats (like Photoshop, Illustrator) and SWF files.
For those who have not bought the subscription, the storage limit is upto 2GB
Regards,
Rahul Tyagi
