Disk space full when recording

I seem to be getting the same error every time I record: “Audio recording aborted. The Disk is full”. However, I have got 49.8GB of free space on my disk and I do not know what to do. Last time I removed some audio files from the Audio folder that I did not need any more but the problem has resurfaced again and I do not know what to do about it. Please help. Screenshots of the error and space below:
