I tinker quite a lot with GECK and cannot imagine my game without it. I change the stats of all the weapons and armour I use (Don't worry, my crharacter still gets killed quite often, my game is that cruel:P).
Now, to the point: my data folder is full and I mean, FULL of these .esp backups the GECK creates. It has around 30 GB now, man! O_O . Is it safe to remove these .esp backup files, or will my GECK not work normally if I remove them?
