Unreal engine 5 taking way too much space ?

Hey people so i installed today Unreal Engine 5 and it took like 6 hours to install (which made me think that my hdd was literally in bad state and had to do a defrag) but then later i find out that my Unreal Engine 5 folder (UE_5.0EA) is 213gb on the disk??? but size says 35.9gb
How is this possible, anyone had this issue before ?

Best regards
