Destination Disk Full error

Hello. Started using Recuva to restore files. Ran it once and retrieved a good number of files. When I went to run it again I received an error that the destination disk was full. It said it needs 3 GB of space, but the destination drive has over 200 GB free. Any thoughts why this would be? Thanks.

Does it mean that it needs 3 gb of space, or 200 gb plus another 3 gb?
