Air can help cut down on clutter in your workspace. We've established a method of duplicate file detection that will let you know when you've already uploaded an asset onto a board.
The primary duplicate detection method is by file name. When you upload an asset onto a board that already contains an asset with a matching file name, a dialogue box is presented to make you aware. You have the options to cancel the upload, stack the duplicate as a version of the asset, or upload as a separate file.
Please note that the duplicate detection only works within a single board and is not currently functional workspace-wide or within the asset library.
