Help reduce disk space

[TheElf01]

Hi, sorry my english, after doing root in my dell 11 3180, chromeos 103, is working well (thanks!!!) but i lost more than 1GB disk space

I see a file system.rooted.img is almost 1GB, maybe i can erase a backup or something to recover the lost space? sadly i needed to uninstall cranberry because this, but i really want a rooted android, but with limited space 1GB+ is too much

I was thinking in create a ext2 partition in a SD card and move this file there, then symlink or something... i see the file is in

/mnt/stateful_partition/dev_image/cranberry

/usr/local/cranberry

thanks!
