Air is able to store nearly all file types and valid extensions.
Design files can also be stored in Air, but storage does not guarantee an in-app visual preview. For supported preview formats, see What file types can I preview on Air?
Curious about which files are able to return a visual preview after you upload them to Air? Visit our handy wizard, Will It preview on Air? All you need is the file extension (pdf, jpg, doc ... etc) and the wizard will reveal if you can preview or only store the file on Air.
