Running out of disc space

try running something like treesizefree to track down the used space, and then report the files and locations from unreal that are using the space.

I am running out of disc space on ‘C’ drive.
Working on an open world landscape environment. But “disc space” problem is giving me a tough time. I have my Unreal setup location in a different drive where I have more than 100 GB free space. But Unreal is eating my disc space from ‘C’ drive, where I have only 20 GB of free. If I keep working for an hour it comes to less than 500mb and Unreal editor crashes.

Please let me know the solution.
