That’ll do, thanks!
Piped the output to a file, then fired up WSL and ran dos2unix on it. I was then able to use egrep to find any files with sizes >= 1 GB:
ben@Helios:/mnt/c/Users/bensh/Desktop$ cat duplicati.txt | egrep 'GB\)$'
C:\Users\bensh\.android\avd\Nexus_5X_API_28.avd\snapshots\default_boot\ram.img (1.50 GB)
C:\Users\bensh\.android\avd\Nexus_5X_API_28.avd\userdata-qemu.img (6.00 GB)
C:\Users\bensh\.android\avd\Nexus_5X_API_28.avd\userdata-qemu.img.qcow2 (2.01 GB)
C:\Users\bensh\Documents\soundfonts\CrisisGeneralMidi3.01.sf2 (1.57 GB)
Edit: Yep, I was able to reduce my source data size from around 35GB to around 25GB via the exercise, as I suspected. Thanks all.
