Free space reduced in lubuntu after an audacity crash

I tried to work with an audio file of size 448MB. When I tried to open it using Audacity, I saw that my linux partition was gradually losing free space. When the free space reduce to 0 bytes from 4GB or so, the audacity software crashed. But now even after restart, the free space is not retrieved back.

Please can anyone help me?

I tried to see the .audacity-data folder, but it has very less disk usage…
