Exporting separate tracks have really big size

[stevenmaybank]

Hi I had a long mix that I split with CD markers to export into seperate tracks, but when exporting each track is exporting at the size of 2.99gb each and I ain't a clue why they are so big. Does anyone know how to fix this issue?

I'm afraid that we'd need a lot more information than that before we could even begin to work out what's happening here. For a start, how long is 'long'?

The mix is 22hours long but the separate tracks are only few minutes long. I tried to export just one track and it was still 2.99gb
